| High Light | loop detector with pulse output ，vehicle presence detector for barrier gates ，AC DC loop sensor detector | ||
The vehicle loop detector (also known as a loop sensor) is a cornerstone of modern intelligent transportation and access control solutions, engineered to deliver precise, consistent vehicle detection across diverse indoor and outdoor environments. Whether it's a parking loop sensor for car park management, a gate loop detector for automated barrier systems, or a traffic loop detector for intersection control, this professional-grade device excels at identifying cars, trucks, motorcycles, forklifts, and other vehicles—making it indispensable for countless commercial, industrial, and public sector applications.
Crafted with versatility and durability in mind, the loop detector integrates seamlessly with inductive loops embedded in roads, driveways, parking bays, and entry points. Unlike conventional sensors, it offers dual operational modes—Presence Mode and Pulse Mode—via independent relay outputs, enabling flexible integration with gate controllers, traffic counters, access management systems, and industrial automation tools. With 16 levels of adjustable sensitivity and configurable DIP switches for delay settings, frequency selection, and auto-reset functions, the vehicle loop detector adapts effortlessly to varying vehicle sizes, loop configurations, and environmental conditions.
