Loop Detector

Model Number: LD-1123-PAQ
The LD-1123-PAQ Loop Detector is designed to be used with gates or other vehicle detection systems. The unit connected to an input loop which is buried in the pavement. If a vehicle is over the input loop, the detector sends a signal to perform such actions as opening a gate, holding a gate open, or indicating that a vehicle is in a bay.
