Vehicle Presence Relay Loop Detector Offering DIP Switch Adjustable Frequency and Supported Automatic Reset for Parking Access Control
The LD-100 and LD-102 are advanced single-channel inductive vehicle loop detectors designed specifically for parking barrier gates, vehicle entrances, access control systems, and various traffic detection applications. These reliable sensors effectively detect vehicles by monitoring changes in an inductive loop embedded in the road surface, providing precise vehicle presence detection for seamless operational control.
Operating as a sophisticated single channel loop detector, the device works by continuously sensing the inductive loop installed beneath the pavement. When a vehicle enters this loop detection zone, the detector identifies the change in the loop's condition caused by the vehicle's metallic mass. It then outputs relay signals to connected barrier gates or control systems, enabling automated responses such as gate opening or traffic monitoring.
Engineered as a dependable parking barrier loop detector and vehicle presence detector, the LD-100/LD-102 series offers multiple configurable features verified for high performance. These include 16 selectable sensitivity levels to fine-tune detection accuracy, a dedicated Presence Relay A, and a configurable Relay B for customized output control.
The product line includes two distinct power versions tailored to different installation requirements: the LD-100 model operates on a wide input voltage range of 100–240 VAC, while the LD-102 model is designed for 12–24 VAC/DC power supply.
