INTRA transfers inductive signals from one or multiple Bircher SafeTecâ sensing edges to an electronic unit for evaluation. The redundant evaluation meets the requirements of the German standard ZH1/494 for professional 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.
