Vehicle Detectors
Product Description
Sensable vehicle detectors are inductive loop detectors used to detect the presence and movement of vehicles in:
- Parking barriers
- Boom gates
- Industrial doors
- Access control systems
Operating Principle
- A loop cable is installed in the ground to form a rectangular loop
- The detector monitors the loop’s inductance field
- When a vehicle passes over:
- Metal mass changes the field
- Detector activates output relay
