Fork type photoelectric sensor OVP4-75.10.FK
Sn=30mm, PNP/NO+NC, 10-30VDC, 250mA, 75x18x52mm
The OVP4-75.10.FK infrared photoelectric fork type sensor for direct current consists of a receiver and transmitter which are located in a metal housing 75x18x52mm. The output of the optical fork sensor is PNP type with one normally open and one normally closed contact. The width of the air slot of the photoelectric sensor is 30mm. The optoelectronic slotted 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 fork optical sensor. The sensor's outputs are protected of overload and short circuit.
Application and operating principle
The OVP4-75 presented photoelectric fork type 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 optical sensor output switches from one state to another. The optoelectronic fork sensor has a good resolution (1,0 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 OVP4-75 photoelectric and optoelectronic fork type 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 optical sensor is activated when a label passes through its air slot. The photoelectric fork sensor there is a longer period of work due to contactless switching of the electrical circuits in which is included.
