Loop Detectors

LC series loop detectors and in-ground induction loops from Pepperl+Fuchs create a universal sensor system for the reliable detection of vehicles such as cars, motorcycles, and bicycles.
 

Application areas for loop detectors:

• Gate control, barrier control
• Position detection in parking garages
• Signal output for traffic light systems, traffic computers, vehicle count
• Protection of transfer stations in automatic conveyor systems
• Direction-dependent vehicle detection
   

How they work:

The wire loops embedded in the ground act as the inductive mechanism for a high-frequency oscillating circuit. When a vehicle with metal parts approaches or stops within the wire loop, the frequency of the oscillating circuit changes. The signal output reliably detects the vehicle using potential-free relays. The dimensions of the detection range vary based on the size and shape of the induction loops.
