Siemens AG 29 General data 3SE5 Overview Position switches in the innovative SIRIUS 3SE5 series are modern in design, compact, modular and simple to connect. Complete units Popular versions of the position switches in standard enclosures are available as complete units. Position switches with plastic and metal enclosures Modular system The 3SE5 series features a new modular system comprising different sizes of the basic switch and an actuator which must be ordered separately. Thanks to the modular design of the switch the user can select the right solution for his application from numerous versions and install it himself in a very short time. The short delivery times of the modules enable fast replacement and thus ensure high plant availability. Design Enclosure sizes The 3SE5 switches are available in five different enclosure sizes: Open-type position switch IP2 or IP1 Plastic enclosures according to EN 547 (31 mm wide), 1 cable entry Plastic enclosures (5 mm wide), 2 cable entries Metal enclosures according to EN 541 (4 mm wide), 1 cable entry Metal enclosures (56 mm wide), 3 cable entries The following items are available in addition from the 3SE2 series: Plastic enclosure according to EN 541, 4 mm wide Metal enclosures with 3 or 4 contacts, 56 mm wide Enclosure versions Various basic switches can be selected for the enclosures: With switching elements with two or three contacts (screw terminals) designed as slow-action or snap-action contacts Optional LED status display With mounted four or five-pole M12 connector socket (available for the wide enclosures as an accessory for self-assembly) With 6-pole connector socket + PE on the metal enclosures With increased corrosion protection Metal enclosures for explosion protection (ATEX) (see page /55) AS-Interface version with integrated ASIsafe electronics for all enclosure designs (see page /56) Actuator variants The following actuator variants are available: Rounded plungers Roller plungers Roller lever Angular roller lever Spring rod Twist levers and rod actuators Fork lever The actuator rollers are available with various materials and diameters. Examples of selection options in the modular system 3SE2 series The position switches of the 3SE2 series are still available, in particular those switch versions which are not yet covered by the new 3SE5 series, including the complete 3SE2 23 series with 4 mm plastic enclosure or additional switching element versions, e. g. with make-before-break, with 2 NO contacts and with 3 or 4 contacts. NSC_29 Twist actuators for twist levers and rod actuators, with setting of switching to right, left or right/left (standard for all twist actuators except fork levers) /4 Siemens LV 1 T 29

Siemens AG 29 General data 3SE5 Optional LED indicators LED indicators available for all enclosure sizes Mounting Easy plug-in method for fast replacement of the actuator head The enclosure versions can be supplied with an LED signaling indicator (1 green + 1 yellow). This is the first time that optical status monitoring is also available for small standard enclosures according to EN 547. The LED signaling indicators are available in all common voltages (24 V DC and 23 V AC). Additional contacts Exchangeable two and three-pole switching blocks for all enclosure sizes (1) Open cover (2) Actuate locking lever (3) Replace the head (turnable by 16 x.5 ) (4) Lock and close the cover Fast connection method For plastic enclosure with a width of 31 mm The new three-pole switching block (2 NC, 1 NO) in snap-action and slow-action is regularly available for all enclosure forms. It offers more switching through redundant shutdowns (2 NC contacts) with simultaneous signaling (1 NO contact). The same installation space is required as for a two-pole switching block. Contact reliability The new switching blocks ensure an extremely high contact stability. This applies even when the devices are switching low voltages and currents, e. g. 1 ma at 5 V DC. Positive opening q The NC contacts of the switch are forced open mechanically, positively-driven and reliably by the plunger. This is referred to as "positive opening". These position switches can be wired quickly and easily as an added customer benefit. The connecting cable is first connected to the terminals of the contact block and then guided through a slit into the cable gland opening. The time saved through this new connection method is approx. 2 to 25 %. Online configurator The online configurator helps you not only to select and order the right switch but also to create complete product documentation.

Siemens AG 29 General data 3SE2, 3SE3 Overview With the SIRIUS standard position switches, mechanical positions of moved machine parts are converted into electrical signals. Through their modular and uniform design and large number of variants, the devices can meet practically all requirements in industry. Scope of supply The 3SE2 position switches are supplied as standard as complete units. Available in addition are basic switches without an operating mechanism which are used preferably for types of operating mechanisms not found in the standard range. Switch versions which have been replaced by the new 3SE5 devices are no longer in the standard range. Design Enclosure sizes The 3SE2 switches are available in different enclosure sizes: Plastic enclosures according to EN 547 (31 mm wide), 1 cable entry Plastic enclosures according to EN 541 (4 mm wide), 1 cable entry Plastic enclosures (5 mm wide), 2 cable entries Metal enclosures according to EN 541 (4 mm wide), 1 cable entry Metal enclosures (56 mm wide), 3 cable entries The following items are available in addition in the 3SE3 series: IP2 open-type position switches Compact position switches with metal enclosure and molded cable Enclosure versions Various basic switches can be selected for the 3SE2 series: Standard enclosures (plastic or metal) with two slow-action or snap-action contacts (screw terminals) Metal enclosures with three slow-action contacts Metal enclosures with four slow-action or snap-action contacts Actuator variants The following actuator variants are available: Rounded plungers Roller plungers Roller lever Angular roller lever Spring rod Twist levers and rod actuators Fork lever /6 Siemens LV 1 T 29

Siemens AG 29 General data 3SE2, 3SE3 Design Enclosure The 3SE2 position switches are in either a narrow or wide enclosure made of fiber-glass strengthened, flame-retardant plastic or cast aluminum. The position switches in a narrow enclosure comply with the standards in terms of their enclosure and actuator as well as their fixing dimensions and operating points: EN 547 for rounded plunger, roller plunger, roller lever and twist lever actuators - 3SE2 2 series with plastic enclosure EN 541 for rounded plunger, roller plunger, twist lever and rod actuators - 3SE2 23 series with plastic enclosure - 3SE2 12 series with metal enclosure The narrow enclosures have one and the wide enclosures have Contacts two or three cable entries, suitable for looping through cables. The cable entry has a metric thread M2 1.5 for cable glands with 6 mm long threads (see Accessories). To secure position switches with a safety function against changes in their position, keyed techniques must be employed on installation, such as: Fixing by means of round holes Contact reliability For longitudinal holes, guide pins and stops must also be used. Actuators All actuators can be retro-fitted or exchanged for another version. They can also be repositioned every 9 so that the switches can be operated from any of the four sides. Important: The position switches must not be used as an end stop. Standard, rounded and roller plungers Operation in direction of the plunger axis or in case of roller plunger with bar at right angles to the plunger axis. Rounded and roller plungers have an additional overtravel and hence a large operating distance. The roller plunger is recommended for lateral actuation and relatively long overtravel. Roller and angular roller levers For a high starting speed of v max = 2.5 m/s For actuators made of finely ground steel in the form of cams, straight-edges or cam disks Very long mechanical endurance Spring rod Can be used for undefined actuations and changing starting conditions Function Starting from any direction Positive opening q Twist levers and rod actuators For a high starting speed of v max = 3 m/s Variety of starting options Insensitive to oil, dirt, grinding dust, ice and coarse-grained material With the twist lever the maximum approach angle is always equal to the maximum trailing angle. The rod actuator must be used when no actuation with approach and trailing angle is possible. Fork lever Switchable in two directions For reciprocating movements Latched actuator Rounded plungers with short-stroke contact block Exact switching response Operating travel and hysteresis greatly reduced Optimized wear characteristics Suitable for the monitoring of doors and access flaps up to Category 4 according to ISO 49-1 (EN 954-1) Rounded and roller plungers with central fixing Fast mounting with M1 1 thread Easy adjustment Same mounting type as the proximity switch BERO The position switches with plastic enclosures are available with 2 contacts; the position switches with metal enclosures are available with 2, 3 or 4 contacts. The contacts can be snap-action contacts, slow-action contacts or slow-action make-beforebreak contacts. The contacts are designed for a thermal current of 1 A. The movable contacts are double-break contacts. This ensures an extremely high contact stability, even when the devices are switching low voltages and currents, e. g. 5 V DC/1 ma. As the moving double-break contacts are electrically isolated from each other, the position switches can also switch, without any reservations, circuits up to 3 V with different potentials. The operating point of the snap-action contacts is independent of the contact erosion. The contact chamber is covered to prevent ingress of foreign bodies. Connection Metric thread M2 1.5 for mounting glands, connector sockets or adapters Expansion range with mounted connector socket With AS-Interface F adapter for direct connection to ASIsafe; usable up to Category 2 according to ISO 49-1 (EN 954-1). With AS-Interface F adapter for direct connection to ASIsafe; with additional M12 connector socket for connection of the second position switch, usable up to Category 4 according to ISO 49-1 (EN 954-1). The NC contacts of the switch are forced open mechanically, positively-driven and reliably by the plunger. This is referred to as "positive opening". In order to ensure this positive opening, the position switches must be actuated in such a way that the nominal values for the positive opening are substantially exceeded. Siemens LV 1 T 29 /7

Siemens AG 29 3SE3, metal enclosures, compact design with molded cable Overview In harsh industrial environments and in installations with limited space, the small 3SE3 16 and 3SE3 1 compact switches are ideal. The switches are already equipped with a molded cable of 2 m in length and can therefore be installed in the smallest of spaces. Both the enclosure and the actuator head are made of metal and comply with the high IP67 degree of protection. The roller plunger, rounded plunger and twist lever are available as twist actuators. The contact block is designed with snap-action contacts 1 NO + 1 NC. The NC contact complies with the requirements for positive opening acc. to IEC 6947-5-1. The 3SE3 1 position switch with molded cable is available in different sizes: The 3SE3 1 series complies with the EU standard and features a 3 mm wide enclosure with drilled holes at a distance of 2 mm.

With Separate Actuator General data Siemens AG 29 Overview Position switches with separate actuator are used where the position of doors, covers or protective grills must be monitored for safety reasons. 3SE5 position switches with separate actuator have the same enclosures as the standard switches (modular system). Operation The actuator head is included in the scope of supply. For actuation from four directions it can be adjusted through 4 x 9. The switches can also be approached from above. The actuator head of the 3SE2 243 and 3SE2 257 switches with special enclosures cannot be changed. The switches can be approached from the two broad sides and from above. The actuators are not included in the scope of supply of the position switches and must be ordered separately from a choice of six versions to suit the application. The actuator is encoded. Simple overruling by hand or auxiliary devices is impossible. Radius actuators The position switches with radius actuators are particularly suitable for rotatable protective devices. The movable actuation key allows even small radii to be approached. Damage to the switch and the actuator due to inaccurate approach is prevented. Locking devices A high-grade steel blocking insert for attaching up to eight padlocks is available for even more safety. Design Enclosure sizes The 3SE5 switches are available in various enclosure sizes: Plastic enclosures according to EN 547 (31 mm wide), 1 cable entry Plastic enclosures (5 mm wide), 2 cable entries Metal enclosures according to EN 541 (4 mm wide), 1 cable entry Metal enclosures (56 mm wide), 3 cable entries Also available is a switch in the 3SE2 series, which has arisen in this form according to general market requirements: Plastic enclosures outside of the standards, enclosure width 52 mm. Enclosure versions Various basic versions can be selected for the enclosures of the 3SE5 series: Available with two- or three-pole switching elements designed as slow-action contacts Optional LED status display With mounted four or five-pole M12 connector socket (available for the wide enclosures as an accessory for self-assembly) With 6-pole connector socket + PE on the metal enclosures Similarly with a combination of connector socket and LED indicators With increased corrosion protection Metal enclosures for explosion protection (ATEX) (see page /55) AS-Interface version with integrated ASIsafe electronics for all enclosure designs (see page /56) Blocking inserts with padlock Dust protection A rubber cap to protect the actuator head from contamination is available for operation in dusty environments. Contact reliability The new switching blocks ensure an extremely high contact stability. This applies even when the devices are switching low voltages and currents, e. g. 1 ma at 5 V DC. Positive opening q The NC contacts of the switch are forced open mechanically, positively-driven and reliably by the plunger. This is referred to as "positive opening". /4 Siemens LV 1 T 29

Siemens AG 29 With Solenoid Interlocking General data Overview The position switches with solenoid interlocking are exceptional, technically safe devices which restrict and prevent an unforeseen or intentional opening of protective doors, protective grilles or other covers as long as a dangerous situation is present (i. e. follow-on motion of the shutdown machine). The safety position switches with solenoid interlocking are comprised of a switch part with electromechanical interlock and a mechanical actuator which has to be ordered separately. They are rugged protective devices that enable the greatest possible safety for man and machine. The position switches with solenoid interlocking are offered in plastic or metal enclosures. Dimensions (W H D): 3SE5 3: 54 mm 15 mm 43.5 mm, 3SE2 : 9 mm 1 mm (+ head 41.3 mm) 45 mm. Operation The actuator head is included in the scope of supply. For actuation from four directions it can be adjusted through 4 x 9. The 3SE5 3 switches can also be approached from above. The actuators are not included in the scope of supply of the position switches and must be ordered separately from a choice of six versions to suit the application. Actuation data: Maximum actuating speed v max = 1.5 m/s Minimum actuating speed v min =.4 mm/s Minimum force in the direction of actuation F min = 3 N The actuator is encoded. Simple overruling by hand or auxiliary devices is impossible. Radius actuators The position switches with radius actuators are particularly suitable for rotatable protective devices. The movable actuation key allows even small radii to be approached. Damage to the switch and the actuator due to inaccurate approach is prevented. Locking devices A high-grade steel blocking insert for attaching up to eight padlocks is available for even more safety. Dust protection A rubber cap to protect the actuator head from contamination is available for operation in dusty environments. Solenoid interlocking There are two versions for locking the actuator: Spring-actuated lock (closed-circuit principle) with various release mechanisms Magnetic field lock (open-circuit principle) The spring-actuated switch is equipped with an auxiliary release for emergency situations or setup mode. Available as options (only 3SE5): Escape release or Emergency release Contact blocks The position switches with solenoid interlocking have one switching block each for: Monitoring the actuator or the position of the protective door Monitoring the position of the solenoid The mechanical design of the switch corresponds to the requirements of the failsafe principle to EN 1. Optical signaling equipment The position switches with solenoid interlocking are available with an optional optical signaling device. The signaling device indicates the switch position of the lock and the protective device optically by means of 2 LEDs on the front. Protective device Solenoid Display Meaning interlocking Closed Released Actuator to be pulled Closed Closed Actuator locked Open Open Actuator pulled Note: The voltage of the LEDs at the monitored contacts must be the same as the operational voltage of the magnet (same potential).

Siemens AG 29 3SE6 Magnetically Operated Switches Magnetic monitoring systems Overview Design NSC_637a 2 4 5 5,5 6 3 4 5 5 5,5 4 6 3 2 1 A magnetically operated switch is comprised of a coded switching magnet and a switching element (sensor unit). Evaluation requires a safety relay or connection to a bus system. Enabling range (example) A magnetic monitoring system is comprised of a coded switching magnet, a contact block (sensor unit) and a monitoring device (see Function). The contact block and switching magnet must not be installed on ferromagnetic materials because the switching response will be influenced. Spacers can be used to prevent this. The contact blocks are available with either a connecting cable or connector. Function 3SE6 6 safety relay The 3SE6 6 safety relay has two floating enabling circuits (safe circuits) as NO contact circuits and one floating signaling circuit as a NC circuit. The number of enabling circuits can be increased by adding one or more 3TK2 3 expansion modules. Up to six protective devices (sensors) can be connected to the safety relay. The device has six current-sourcing semiconductor outputs (Y1... Y6), which report the state of the connected protective devices. Combination of monitoring units and magnetically operated switches Crossovers between the sensor circuits as well as ground faults and open circuits are detected by an internal monitor. The device is protected by an internal self-restoring PTC fuse (multifuse).
