Price 49.4 EUR no VAT

The ORP3-60.20.FKT infrared photoelectric retro-reflective sensor for direct current consists of a receiver and transmitter which are located in a parallelepipedal plastic housing 38x15x60mm. The output of the optical sensor is NPN type with one normally open and one normally closed contact. When using a Ø82mm reflector, the maximum distance of operation of the retro-reflective photoelectric sensor is 5m. 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 presented ORP3-60 photoelectric reflective sensor serves to switch direct current circuits. The optical sensor emits infrared modulated ray of light which reflects on a reflector and returns back to the sensor. When an object passes between the sensor and the reflector, the ray of light becomes disconnected and the output of the sensor change state. When there is reflector in front of the sensor, the output indicator is on. The optical sensor has a potentiometer to adjust the sensitivity.

Short description

The ORP3-60 square optoelectronic reflective sensor which is used in industrial systems, as electronic automation equipment for switching at 3-wire and 4-wire electrical circuits of direct current. The sensor switches the electrical circuit in which it is connected when an object passes between it and the reflector. The reflective photoelectric sensor there is a longer period of work due to contactless switching of the electrical circuits in which is included.
