Loop detectors

Carlo Gavazzi's loop detector for vehicle detection continues our tradition of providing superior sensing technology and solutions for the door and entrance control market. The pulse mode relay can be configured to be activated when a vehicle enters or leaves the loop. The output signal is useful for controlling all kinds of doors, shutters, swing gates and sliding gates etc.
