Safety Single-channel Inductive Vehicle Loop Detector Sensor Vehicle Toll Collection System Door Automatically Opens ,Long Lasting

This is a single channel induction loop detector. The principle is based on changes in loop inductance, which are caused by the metallic components of passing vehicles. These changes are received and evaluated by the microprocessor. Calibrated when operating voltage is applied, easy to use When the DIP switch is turned to the position or the output time is changed, the self-test will be completed
