Vehicle Presence Detector with Pulse Output Loop Sensor for Barrier
Gates AC DC
High-Performance Vehicle Loop 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.
Key Advantages of Our Loop Sensor
- Universal Vehicle Detection: Reliably identifies cars, trucks, motorcycles, forklifts, and
commercial vehicles, eliminating false triggers and ensuring
consistent performance.
- Dual Operational Modes: Presence Mode for continuous vehicle monitoring (e.g., parking bay
occupancy) and Pulse Mode for counting or trigger-based actions
(e.g., gate activation), maximizing usability.
- Flexible Power Options: Available in two models—LD100 (100-240V AC) and LD102 (12-24V
DC)—to suit indoor, outdoor, and mobile applications.
- Weatherproof & Durable: Rugged housing designed for both indoor and outdoor use,
withstanding extreme temperatures and high humidity.
- Extended Compatibility: Supports a wide loop inductance range and long installation
distances (with shielded cable), offering flexibility in layout.
