Fork type photoelectric sensor OVM1-18.24.F

Sn=4mm, NPN/2xNO, 8-30VDC, 100mA, M18x60mm, with two dephased outputs

Price 48.83 EUR no VAT

The OVM1-18.24.F fork type infrared photoelectric sensor for direct current with dephased outputs consists of a receiver and transmitter which are located in a cylindrical metal housing M18x60mm. The sensor has two normally open NPN outputs. 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 2 m and has an LED indicator showing the state of the outputs of the optical sensor. The sensor's outputs are not protected of short circuit.

FEATURES

The M18 photoelectric fork type sensor has two output signals A and B, which are shifted on phase of 90° (at raster of the observed object 0,5mm). It is used as a sensor to measure the angular and linear displacements, as well as to determine the direction of rotation of shafts or linearly moving objects. The principle of operation consists in the emitting and the receiving an unmodulated (constant) light ray in the infrared area of the spectrum. The sensor has a good resolution (0.5 mm). The output indicators of the signals A and B light up when there is no object in the working gap.

Short description

These is M18 fork type infrared photoelectric and optoelectronic sensor with two dephased outputs which is used in industrial systems, as electronic automation equipment. When passing a nontransparent object in the air gap the sensor's outputs are switched successively. The fork type photoelectric sensor there is a longer period of work due to contactless switching of the electrical circuits in which is included.
