Waterproof Reflective Laser Photoelectric Switch Sensor Detector NPN with Relay 20m 6-36VDC E3F

The laser and reflector are installed opposite each other at a distance of up to 20 m. The installation height depends on the terrain and the expected movement of the attacker. The laser beam (invisible to the human eye) is constantly directed at the reflector and, when crossed, transmits an alarm signal to the security system. The barrier is powered from 6-36 volts DC and it is possible to use the barrier at subzero temperatures down to minus 35 degrees, which allows the wireless barrier to be used outdoors all year round.
