2 Compact Size Sensor NA-PK SERIES 498 APPICATIONS Cell production line Assembly line PHOTO PHOTO BASIC PERFORMANCE No synchronization wires required Synchronization wires are not required, due to the utilization of a synchronized scanning system that results in a reduction of wiring man-hours. In addition, the sensors can be switched among three different emission frequencies, allowing up to three sets of sensors to be installed closely together in the same vertical plane, without causing mutual interference. Even when installed in multistage shelving, malfunctions due to mutual interference will not occur. (When mounted horizontally, a maximum of two sensor sets may be used side-byside, without interference.) FUNCTIONS Switchable output operation Output operation can be switched to suit the desired application. Sensor protection brackets are available Sensor protection brackets are now available (optional), to protect sensors from damage due to tools and other objects. The protection brackets have a black coating, which enhances the visual effectiveness of the job indicator. MEASURE MOUNTING Easy alignment The sensor s beam axis is directly in line with the mounting holes, making sensor alignment easier. Mounting can be performed simply by using M4 nuts. Mounting hole Flexible cable orientation The cabling can be oriented in either of the two different directions: downward or sideways, thus permitting a flexible layout, in accordance with the sensor s mounting position.

Make sure that the power supply is off while setting the selection switch. State of operation / frequency selection switch Never use this product as a sensing device for personnel protection. For sensing devices to be used as safety devices for press machines or for personnel protection, use products which meet standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country. If this product is used as a sensing device for personnel protection, death or serious body injury could result. For a product which meets safety standards, use the following products. Type 4: SF4B series Type : SFB series M4 screws with washers M4 nuts Output operation OFF when one or more beams are interrupted. ON when one or more beams are interrupted.

7 5 Compact Size Sensor NA-PK SERIES Wiring PRECAUTIONS FOR PROPER Make sure that the power supply is off while wiring and setting the selection switch. Take care that wrong wiring may damage the sensor. Verify that the supply voltage variation is within the rating. If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground. In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of the sensor, connect the frame ground (F.G.) terminal of the equipment to an actual ground. Extension up to total m 8.84 ft is possible with. mm, or more, cable for both emitter and receiver. However, in order to reduce noise, make the wiring as short as possible. Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction. DIMENSIONS (Unit: mm in) Refer to General precautions. Make sure to use an isolation transformer for the DC power supply. If an auto-transformer (single winding transformer) is used, this product or the power supply may get damaged. In case a surge is generated in the used power supply, connect a surge absorber to the supply and absorb the surge. s Do not use during the initial transient time (.5 sec.) after the power supply is switched on. Take care that the sensor is not directly exposed to fluorescent light from a rapid-starter lamp or a high frequency lighting device, as it may affect the sensing performance. Avoid dust, dirt, and steam. Take care that the product does not come in direct contact with water, oil, grease or organic solvents, such as, thinner, etc. To select the switch, a minus screwdriver is necessary.
