The loop sensor—alternatively called a vehicle loop detector or traffic loop sensor—stands as a robust, all-purpose vehicle detection solution engineered to elevate the efficiency of access control systems and traffic management setups. Crafted to thrive in both indoor and outdoor environments, this device offers precise detection of cars, trucks, motorcycles, and commercial vehicles, making it a go-to choice for diverse scenarios ranging from residential gate access to busy highway traffic monitoring.

What sets this loop sensor apart is its adjustable frequency feature, with a 4-step selectable range of 20-80 kHz. This allows technicians to fine-tune the device to avoid signal interference from nearby loops, metal infrastructure, or electronic equipment—ensuring consistent performance even in crowded access control points or high-traffic intersections. Complemented by a rugged weatherproof housing (IP-rated for dust and water resistance), it braves rain, snow, dust, and extreme temperatures (-40°C to +70°C), delivering unwavering reliability in exposed outdoor settings or harsh industrial access areas.

• Customizable Frequency for Anti-Interference: 4-step adjustable frequency (20-80 kHz) eliminates cross-talk with adjacent devices, guaranteeing accurate detection in complex access control and traffic environments.
• Weatherproof & Durable Construction: IP-rated housing shields internal components from the elements, making it suitable for outdoor access gates, road intersections, and exposed toll booths.
• Dual Relay Outputs for Flexibility: Presence Relay (for continuous vehicle monitoring) and Pulse/Fault Relay (for trigger-based actions like gate activation or traffic signal triggering) enable seamless integration with diverse systems.
• Wide Sensitivity Range: 16-level adjustable sensitivity (0.010% to 2.56% DL/L) ensures reliable detection of vehicles of all sizes, from lightweight motorcycles to heavy-duty trucks.
• Dual Power Compatibility: Supports 100-240V AC (for permanent installations) and 12-24V DC (for mobile or off-grid access control setups), adapting to varied power requirements.

This versatile loop sensor excels in:

• Residential & Commercial Access Control: Gate automation for communities, office parks, and retail centers, ensuring secure vehicle entry/exit.
• Traffic Signal Management: Intersection vehicle presence detection to optimize signal timing and reduce congestion.
• Toll Collection & Checkpoints: Vehicle detection for automated toll booths, border checkpoints, and security screening areas.
• Industrial Access Management: Factory and warehouse vehicle access control, preventing unauthorized entry to restricted zones.
• Public Transit Facilities: Detection of buses, shuttles, and service vehicles at airports, train stations, and bus terminals.
• Highway & Road Monitoring: Traffic flow counting, congestion detection, and data collection for transportation planning.
• Parking Lot Systems: Entry/exit barrier control and occupancy monitoring for commercial parking facilities, malls, and stadiums.
• Specialized Access Points: Vehicle detection for drive-throughs, car washes, and EV charging stations.

Engineered for adaptability and durability, this loop sensor combines adjustable frequency, weatherproof design, and flexible integration to meet the demands of modern access control and traffic management. It's a reliable choice for facility managers, traffic engineers, and security professionals seeking a high-performance vehicle detection solution that delivers consistent results in any environment. Backed by a 2-year warranty and round-the-clock support, it's an investment that ensures long-term operational efficiency.
