Fork type photoelectric sensor OVP4-70.10.RKT
Sn=10mm, PNP/NO+NC, 9÷36VDC, 250mA, 70x24x35mm
The OVP4-70.10.RKT fork type photoelectric sensor for direct current consists of a receiver and transmitter which are located in a plastic housing 70x24x35mm. It works with red light and is used for counting and positioning labels. 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 10mm. 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 slot sensor is protected against incorrect cable connection, current overload and short circuit of the outputs.
Application and operating principle
The OVP4-70 fork type photoelectric sensor consists of a transmitter and a receiver located in one housing. The principle of operation consists in the emitting and the receiving a modulated light ray in the visible area of the spectrum. The sensor is used in labelling machines for positioning and counting of labels located on a transparent or translucent carrier tape. The distance between the labels should not be less than 1mm. The sensor can register labels moving at speeds of up to 200 pcs./sec. The sensor output indicator lights up when there is no label in the slot between the transmitter and the receiver.

Short description
The OVP4-70 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.
