  TYD-120, the single channel inductive loop detector is used wherever vehicles (metal) have to be detected. It can be applied to parking management system, highway fare collection system and traffic lights control mechanism, etc. Single channel refers that the detector can only detect one coil or loop at a time. It has two relays for signal output, users are free to choose either or bother of the connections to count vehicles, control mechanical driver like barrier or card dispenser, etc.
