M18 through-beam photoelectric sensor OBP1-18.10.FKL

The presented M18/L photoelectric through-beam switch is used for operation in a wide range of ambient light - from dark to direct sunlight without changing its sensitivity and operating distance (Sn). Can be used indoors and outdoors. It is designed for switching direct current electrical circuits. The sensor is a system of two housings - transmitter and receiver, located opposite each other. They are interconnected by a modulated infrared light beam. When an object passes between the emitter and the receiver, the light beam is interrupted and the output of the receiver is switched from one state to another. The receiver output indicator lights up when the receiver output is active.

The M18/L optoelectronic barrier sensor is used in industrial systems, as electronic automation equipment for switching at 3-wire and 4-wire electrical circuits of direct current. When passing a nontransparent object between the receiver and the transmitter, the optical connection breaks and the receiver's output switches. The barrier photoelectric sensor there is a longer period of work due to contactless switching of the electrical circuits in which is included.
