Function: LC20-1-DR 230VAC

In combination with wire loops laid in the floor, loop detectors form a universal sensor system for detecting vehicles. When vehicles drive onto the loop, the resonance frequency changes. Intelligent automatic frequency selection (AFS) reduces setup time and simplifies the installation of complex multi-lane entrances. The evaluation process automatically and cyclically adjusts to the respective loop, so that changes in loop inductance due to temperature, humidity or component ageing are automatically compensated.
