Bircher SafeTec safety edges are pressure sensitive devices used for stopping or reversing automated doors and gates upon touching a person or object. They are also used in machinery, conveyors, stage lifts, material lifts and numerous other applications with pinch points or trapping hazards. Together with a Bircher SafeTec controller or switching unit they offer a reliable safety system with the controller providing the interface to the machine or motor controls. You can define any length of the edges, the minimal length is 10 cm.

Inductive Transmission System

INTRA transfers inductive signals from one or multiple Bircher SafeTec sensing edges to an electronic unit for evaluation. The redundant evaluation meets the requirements of the German standard ZH1/494 for doors and gates.
The main advantage of INTRA is the capability to monitor sensing edges without mechanical or direct electrical connections between the stationary and moving part of a sliding gate. Compared to conventional sensing edge signal transmission via trailing cable, the INTRA system is virtually maintenance free
