Professional Dual Channel Loop System | Directional Logic & High Sensitivity & Anti-crosstalk interference

The JUTAI Professional Dual Channel Loop System (Models LD-200/LD-202) redefines precision and reliability in advanced traffic management, combining directional vehicle tracking, ultra-high sensitivity, and interference-free operation for mission-critical applications. Engineered with dual-channel directional logic, the system accurately determines vehicle movement (entrance/exit) using time-phase analysis, enabling real-time traffic flow optimization at intersections, toll plazas, and secure facilities. Its 16-level sensitivity adjustment (0-F) ensures precise detection across a 20–2000μH inductance range, capturing everything from bicycles to heavy trucks, while the adaptive anti-crosstalk technology dynamically isolates frequencies between 40–80KHz to eliminate interference from adjacent detectors, 5G towers, or industrial machinery. Built to endure harsh environments, the IP67-rated aluminum housing protects against dust, water, and extreme temperatures (-40°C to +70°C), ensuring reliability in coastal ports, Arctic sites, or urban hubs.

In smart city traffic networks, the LD-202’s directional logic reduces congestion by 30% through adaptive signal timing based on real-time vehicle flow. For high-security zones, dual-channel redundancy ensures continuous monitoring—Channel 1 triggers access gates, while Channel 2 verifies vehicle clearance to prevent tailgating. The anti-crosstalk tech maintains 99.9% accuracy even in EMI-heavy environments like EV charging stations or near high-voltage power lines. A recent deployment at a Middle Eastern airport cut unauthorized entry attempts by 45% through directional analytics and interference-free detection. The system’s universal 12-24V DC/100-240V AC input supports solar and grid power, while Modbus RTU/TCP outputs integrate seamlessly with traffic management platforms for centralized control.

JUTAI emphasizes simplicity and compliance: plug-and-play DIN-rail mounting slashes installation time to 15 minutes, and auto-reset functionality ensures uninterrupted operation during power fluctuations. Certified for CE, FCC, and RoHS, it meets global standards for safety and sustainability. Backed by a 5-year warranty, this system is the ultimate choice for engineers demanding precision, adaptability, and industrial-grade durability—where cutting-edge directional intelligence meets real-world reliability.

Feature

• 5. Automatic Sensitivity Boost (ASB)
  • This feature reliably detects large truck-trailer combinations and high-bed vehicles by automatically boosting the sensitivity to maximum upon vehicle detection, ensuring accurate identification.

• 6. Automatic Environment Drifting Compensation
  • Loop detectors (or other sensors) automatically adjust and calibrate themselves to changes in environmental conditions, maintaining detection accuracy and stability despite varying weather and environmental factors.

• 7. 17 Dip Switch Setting
  • The dip swich design on the shell makes the setting of loop detector easier and clearer, which is very user-friendly for users. Users can set all the functions first and then install the loop detector.

• 8. Dual Channels work Cooperatively or Independently
  • Dual channel loop detector can be used as two single channel versions, Supports two independent detection channels.
  • Also allowing for the simultaneous monitoring of multiple loops, loop detector has the ability to recognize direction in single-channel applications. enhancing the flexibility and accuracy of vehicle detection.

• 9. Anti-crosstalk interference.
  • Through the dip Switch, the frequency of the loop detector can be adjusted to prevent crosstalk interference caused by the installation of two loop coils too close.
