APPLICATION: This single channel vehicle loop detector is designed to accurately sense the presence and passage of cars and small trucks. Ideal for parking lots, barrier gate systems, drive‑through lanes, and access control, it provides stable vehicle detection to improve traffic safety and automation. SELECTABLE PULSE TIME: Features an adjustable pulse relay output, allowing you to choose between 1 second or 0.5 second energizing time. This flexibility helps match different gate operators, barriers, or automation systems, ensuring smoother operation and more precise control over vehicle triggering. RESET SWITCH: Equipped with a convenient manual reset switch for quick commissioning, maintenance, and fault testing. A simple press forces the detector to retune the sensing loop, recalibrating sensitivity so it can adapt to environmental changes and remain ready for reliable vehicle detection at all times. PULSE RELAY SELECTION: The pulse relay can be configured to activate when a vehicle is first detected or when it exits the loop area. This allows customized integration with parking gates, boom barriers, and traffic lights, supporting both entry and exit control scenarios for greater installation flexibility. PERMANENT OPTION: Offers a permanent presence detection mode that keeps the vehicle recognized even when parked above the loop for extended periods. This prevents false releases of barriers or gates, improving long‑term reliability in parking lots, security checkpoints, loading zones, and driveway monitoring.
