Loop detectors have a magnetic field that can sense when a motor vehicle is present. It sends a signal to the gate operator's control board. The control board then tells the gate arm what safe and secure operation to execute, considering the states of the other subsystems.
GVD3 series loop detectors are our popular products for access control and are widely used at industry door for vehicle detection to realize door opening function, also at the barrier gate and toll gate . The loop detector have automatic reset & manual reset function and sensitivity bootstrapping function .With high quality,stable performance and long service-life, the G-TEK GVD series loop detector will be your wise chioce.
