Sn=150mm, NPN/NO+NC, 9-36VDC, 250mA, M12x56mm

Price 31.2 EUR no VAT

The ODP1-12.20.FKT infrared photoelectric diffuse sensor for direct current consists of a receiver and transmitter which are located in a cylindrical plastic housing M12x56mm. The output of the optical sensor is NPN type with one normally open and one normally closed contact. The maximum distance of operation of the diffuse photoelectric sensor is 150mm. The optoelectronic sensor ends with a 4-wire PVC connecting cable with a length of 2m and has an LED indicator showing the output state of the sensor. The optical sensor is protected against incorrect cable connection, current overload and short circuit of the outputs.

Application and operating principle

The M12 presented photoelectric diffuse sensor serves to switch direct current circuits. The optical sensor emits modulated ray of light, which is reflected by the passing (coming near) object and returns back to the sensor. When an object passes in front of the sensor active surface its output switches from one state to another. Nominal switching distance of the sensor is measured by the help of white cardboard with size 100x100 mm. When there is object in front of the sensor, the output indicator is on. The sensor has a potentiometer for adjusting the maximum action distance Sn.

Short description

The M12 diffuse optoelectronic sensor is used in industrial systems, as electronic automation equipment for switching at 3-wire and 4-wire electrical circuits of direct current. When an object passes in front of the active part of the optical sensor, its output switches. The diffuse photoelectric sensor there is a longer period of work due to contactless switching of the electrical circuits in which is included.
