FUNCTIS Twin sensitivity adjuster Automatic interference prevention The SS-A5 amplifi er is incorporated with an automatic interference prevention function. Mutual interference does not occur even if two sensors are mounted adjacently. -delay timer An -delay timer which extends the output signal by a fixed period is incorporated. This is useful when the connected device has a slow response time or when small objects are being sensed and the output signal width is too small. Normal Timer T Timer period: T = 40 ms approx.

5 399 Manually Sensitivity Set Photoelectric Sensor SS-A5 SERIES SH SERIES PRECAUTIS FOR PROPER Refer to p.986 ~ for general precautions and p.390 for precautions of sensor head. COMPENTS CTROL Always use the sensor head and the exclusive amplifi er together as a set. Cable extension for sensor head If the attached sensor head s need to be extended, use two single core shielded s of at least equivalent quality. If a joint terminal or connector is used for extension, refer to the fi gures below. NG Never use this product as a device for personnel protection. In case of using devices for personnel protection, use products which meet laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection appli in each region or country. The shielded extension must be of ø1.45 mm ø0.057 in outer diameter. Connection with joint terminal The beam-emitting and the beam-receiving should be separated from each other as much as possible. OK Connection with metal connector This distance should be as short as possible. Trimming sensor head s Trim the ends of sensor head s as follows. 1 mm 0.47 in 8 mm in 5 mm in In case of the refl ective type sensor heads, with two parallel s, the beam-emitting must be longer than the beam-receiving as shown below. Note: Do not solder the ends. Mounting (Gray) (Black) 40 mm in 1 mm 0.47 in When the amplifi er is fi xed with screws and nuts, the tightening torque should be 0.58 N m or less. M3 (length 0 mm in) screw with washers The beam-emitting and the beam-receiving must not be connected to one metal connector. NG Use two separate metal connectors. Connection to sensor head OK mounting bracket MS-FX-1 (Optional) separated 1 Rotate the lock lever approx. 160 clockwise. Insert the black beam-receiving s yellow inner wire into terminal No. 4 and the outer woven shield wire into terminal No. 3. Wiring The self-diagnosis output does not incorporate a shortcircuit protection circuit. Do not connect it directly to a power supply or a capacitive load. 3 Rotate the lock lever approx. 90 counterclockwise. (The beamreceiving is hooked up.) 4 Press the beam-receiving into the rubber retainer. 5 Insert the gray beam-emitting s brown inner wire into terminal No. 1 and the outer woven shield wire into terminal No.. Note: Close the case cover fi rmly. Not doing so will weaken the shield clamp. s 6 Rotate the lock lever back to the LOCK position. (The beam-emitting is hooked up.) 7 Press the beam-emitting into the rubber retainer. Do not use during the initial transient time (30 ms) after the power supply is switched on.

6 Manually Sensitivity Set Photoelectric Sensor SS-A5 SERIES SH SERIES 400 PRECAUTIS FOR PROPER Refer to p.986 ~ for general precautions and p.390 for precautions of sensor head. Self-diagnosis function The sensor checks the incident light intensity, and if it is reduced due to dirt or dust, or beam misalignment, an output is generated. Sensing condition Sensing output ( indicator) (in the Light- mode) Stability indicator Self-diagnosis output Insufficient beam intensity Insufficient beam interruption Stable light received level Sensing output threshold level Stable dark level (Lights up) (Lights off) Lights up Lights off 1 The self-diagnosis output transistor stays in the state during stable. When the output changes, if the incident light intensity does not reach the stable light received level or the stable dark level, the self-diagnosis output becomes. Further, the self-diagnosis output changes state when the output changes from Light to Dark state. (It is not affected by the mode switch). 3 In case of insuffi cient beam interruption, there will be a time lag before the self-diagnosis output turns. DIMENSIS (Unit: mm in) Timer If the timer mode switch is set to, approx. 40 ms fi xed -delay timer is obtained. This function is useful if the output signal is so short that the connected device cannot respond.
