Fork type photoelectric sensor OVM1-18.10.FK
Sn=4mm, PNP/NO+NC, 11-30VDC, 250mA, M18x60mm
The OVM1-18.10.FK fork type infrared photoelectric sensor for direct current consists of a receiver and transmitter which are located in a cylindrical metal housing M18x60mm. The output of the sensor is PNP type with one normally open and one normally closed contact. The width of the air gap of the optical sensor is 4mm. 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 optical sensor. The sensor's outputs are protected of overload and short circuit.
Application and operating principle
The M18 presented fork type photoelectric sensor serves to switch direct current circuits. The principle of operation consists in the emitting and the receiving an unmodulated (constant) light ray in the infrared area of the spectrum. When an object passes through the sensor slot, the light ray is interrupted and the sensor output switches from one state to another. The sensor has a good resolution (0,5 mm) and is used to measure the revolutions of shafts and other rotating objects. When there is an object in the sensor slot, the output indicator lights up.

Short description
The M18 slot photoelectric and optoelectronic 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 is activated when a label passes through its air gap. The fork type photoelectric sensor there is a longer period of work due to contactless switching of the electrical circuits in which is included.
