The LD-1 is a compact single-channel inductive loop detector that recognizes vehicles through a loop installed in the pavement. Automatic calibration and continuous frequency rebalancing support stable operation, while four adjustable sensitivity levels adapt to different loop sizes and vehicle types. DIN-rail mounting and relay outputs simplify integration with control systems.

When a vehicle enters the loop, the LD-1 activates the presence relay and illuminates the red LED. Relay 2 can provide a continuous output or a pulse, and hold time can be set to 5 minutes or infinite. Low and high frequency selection helps reduce cross-talk between adjacent loops. Loop faults are indicated by the LEDs and automatically rechecked.
