thank you very much for using sunx products. please read this instruction manual carefully and thoroughly for the correct and optimum use of this product. kindly keep this manual in a convenient place for quick reference. cautions 2 h h h h h h make sure to carry out wiring in the power sup- ply off condition. take care that wrong wiring will 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 vicini- ty of this product, connect the frame ground (f.g.) terminal of the equipment to an actual ground. do not run the wires together with high-voltage lines or power lines or put them in the same race- way. this can cause malfunction due to induction. h h h h h h h h take care that the sensor is not directly exposed to fluo- rescent lamp from a rapid-starter lamp or a high frequency lighting device, as it may affect the sensing performance. do not use during the initial transient time (50ms) after the power supply is switched on. extension up to total 100m, or less, is possible with 0.3mm 2 , or more, cable. however, in order to re- duce noise, make the wiring as short as possible. make sure that stress by forcible bend or pulling is not applied directly to the sensor cable joint. this sensor is suitable for indoor use only. do not use this sensor in places having excessive vapor, dust, etc., or where it may come in direct contact with water, or corrosive gas. take care that the sensor does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc. when connecting the mating cable to the connector type sensor, the tightening torque should be 0.4n :/ m or less. instruction manual cx-400 series amplifier built-in photoelectric sensor h h never use this product as a sensing device for personnel protection. in case of using sensing devices for personnel protection, use products which meet standards, such as osha, ansi or iec etc., for personnel protection applicable in each region or country. warning i/o circuit diagrams 4 h connector pin position of the connector type m12 pigtailed type not con- nected 2 output (note) 9
