Parking Loop Sensor Single Channel Detector
The parking loop sensor—tailored as a single-channel truck detection solution—combines high sensitivity, auto-reset functionality, and adjustable delay settings to deliver reliable vehicle sensing for heavy-duty trucks, commercial vehicles, and large passenger cars in parking scenarios. Engineered for precision in parking lots, truck terminals, logistics parks, and commercial parking facilities, this single-channel loop detector excels at identifying large vehicles without false triggers, seamlessly integrating with parking barriers, access control systems, and occupancy monitoring tools.
Designed with truck-specific detection needs in mind, the high-sensitivity parking loop sensor features 16-level adjustable sensitivity (ranging from 0.010% to 2.56% DL/L), ensuring accurate recognition of heavy-duty trucks with thick metal bodies or complex undercarriage structures. Its single-channel design simplifies installation and wiring, while the configurable auto-reset delay (adjustable via DIP switches) allows customization for different parking scenarios—whether it's short-term truck drop-offs or long-term parking. The detector supports dual power options (100-240V AC / 12-24V DC) and comes with a rugged, weatherproof housing, making it suitable for both indoor and outdoor parking environments.
Core Features of Parking Loop Sensor for Truck
