Failsafe Infrared Safety Sensor 772E

Avoid injury and damage from closing the door/gate when there is still an obstacle underneath or in between. This optical safety device protects against unsafe closing of the door or gate.

An invisible beam guards the opening of your gate. If this beam detects an obstacle, the door will immediately reverse and open fully. If the light beam is interrupted by an object below the gate, the gate will not even close.

The maximum distance between the transmitter and receiver is 15 meters.

This photocell set uses a 2-wire technique, to be connected in parallel and connected to the operator (see manual)
