Loop Detector with Dual Relay Output: DIP Switch Configurable for Toll Booth & Parking Systems
The loop detector—equipped with dual relay outputs and DIP switch configurability—is a precision-engineered vehicle detection solution tailored for toll booths and parking systems. Designed to meet the high-demand, high-traffic needs of these scenarios, this professional-grade device reliably detects cars, trucks, commercial vehicles, and motorcycles, enabling seamless integration with toll collection platforms, parking barriers, access control systems, and occupancy monitoring tools.
What sets this loop detector apart is its dual relay output design (Presence Relay + Pulse/Fault Relay) and intuitive DIP switch configuration, allowing technicians to customize delay times, frequency settings, auto-reset functions, and operational modes without complex programming. Whether deployed in busy toll booths for vehicle counting and toll trigger actions, or in parking systems for entry/exit control and space occupancy monitoring, it adapts to diverse workflow requirements with consistent accuracy. Its rugged construction and wide environmental tolerance ensure stable performance in both indoor parking facilities and exposed toll plaza environments.
