MAG vehicle loop detector for barrier gate 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.
As labor cost increasing, traffic detector is becoming a more attractive solution despite its slightly higher cost. It’s innovative technology has solved many limitation of loop detector.
