Dual Channel Loop Detector - Independent Control & Anti-Crosstalk Tech for Smart Traffic Systems & Reliability

The JUTAI Dual Channel Loop Detector (Models LD-200/LD-202) is engineered to revolutionize traffic management with its independent dual-channel control and advanced anti-crosstalk technology, delivering unparalleled reliability for smart city infrastructure. Each channel operates autonomously, enabling simultaneous functions such as vehicle counting (Channel 1) and emergency lane prioritization (Channel 2), all while maintaining seamless coordination. The 40–80KHz frequency tuning dynamically isolates signals to eliminate cross-talk from adjacent detectors, power lines, or 5G networks, ensuring >99.9% accuracy in high-density installations like multi-lane highways or urban intersections. Built for resilience, the IP67-rated aluminum housing protects against dust, water ingress, and extreme temperatures (-40°C to +70°C), making it ideal for round-the-clock operation in harsh environments.

In smart traffic systems, the detector’s independent channels empower adaptive signal control. For instance, Channel 1 can optimize green light duration based on real-time vehicle queues, while Channel 2 monitors pedestrian crossings to prevent conflicts—reducing congestion by up to 25% in pilot projects. The anti-crosstalk technology ensures interference-free performance even in electrically noisy zones like EV charging corridors or industrial parks. With 16-level sensitivity adjustment (0-F) across a 20–2000μH inductance range, it precisely detects vehicles from motorcycles to freight trucks, minimizing false triggers from debris or small animals. A recent deployment in a European smart city reduced traffic violations by 30% through synchronized lane management.

JUTAI prioritizes reliability and integration ease. The universal 12-24V DC/100-240V AC input supports solar and grid power, while SPDT relay outputs interface effortlessly with traffic controllers and IoT platforms. Certified for CE, FCC, and RoHS, it meets global standards for safety and sustainability. Backed by a 5-year warranty and plug-and-play DIN-rail installation, the JUTAI Dual Channel Detector is the cornerstone of intelligent, future-ready traffic networks—where precision, durability, and innovation drive seamless mobility.
