Vehicle loop detector for sliding gate/operator traffic signal control 4-level sensitivity 

Technical parameters:

Vehicle detector is a ring for single induction coil buried digital intelligent metal detector is mainly used to detect vehicles and metal objects. Using SMT technology , including high-performance microprocessors, adaptive and complete with a frequency environmental tracking coil transformer isolation , high brightness panel light-emitting LED instructions multipurpose variety of working conditions , DIP switch can set the sensitivity level and output delay with reset button , the output is TTL mode ( customers may OCL customize the relay signal and the signal output ) of the product-based company developed excellent performance. stable , reasonable price , widely used in parking management, highway toll station signal control and monitoring systems such as bayonet . compatible Panasonic type vehicle detector.

Installation Guide
Loop detector must be installed away from the detection coil as close as possible . Waterproof environment. Loop detector depends largely on whether the good work it is connected to an induction coil . Coil several important parameters include: coil materials, coil shape and Embedment correctly .
