Loop Detector

The FALCO Loop Detector is used to detect the presence of car via inductance loop coil wire. Loop detector is installed inside the barrier gate to verify if vehicle have finished passing through parking access control or parking ticketing lane. After car has completely passed through the boom gate, loop detector will give signal to barrier gate to start closing boom arm.

The FALCO Loop Detector can also help to prevent the gates from closing too soon. When the vehicle is passing through, it will break the circuit and tell the gate to remain open, preventing it from closing on the car. When the barrier arm is descending, MX-300 will trigger the arm to auto-reverse if it detects another vehicle entering to avoid hitting it .

  • Safe, reliable, and efficient.
  • It is easy to install and convenient to use.
  • Suitable for barrier access system.
