The LDD loop detector can be installed in most parking, traffic and vehicle access control applications for the control of barriers, gates, bollards and vehicle access equipment. Automatic frequency tuning and easy sensitivity adjustment provide easy setup and installation. The automatic increase in sensitivity ensures reliable detection of tall vehicles.

The multi-color LED indication allows the user to easily adjust the inductance and indicates installation problems intuitively for easy diagnosis. The individually assigned user-assigned relay mode for 2 SPDT outputs provides easy adaptation to a multitude of applications. Directional logic in the dual-loop version can be used
