The JUTAI High-Performance Vehicle Loop Detector is engineered to deliver unmatched speed and reliability in vehicle detection, designed for demanding environments such as toll lanes, industrial gates, and urban intersections. Featuring a rapid response time of ≤15ms, it ensures instantaneous triggering of barriers or traffic signals, eliminating delays in high-traffic scenarios. With 16-level sensitivity adjustment (0-F), the detector precisely identifies vehicles ranging from motorcycles to heavy trucks (20–2000μH inductance range), while its adaptive frequency adjustment (40–80KHz) blocks interference from adjacent detectors, EV chargers, or power lines. The IP67-rated aluminum housing provides robust protection against dust, water ingress, and extreme temperatures (-40°C to +70°C), ensuring reliable operation in harsh outdoor or industrial settings.

Ideal for smart city infrastructure and logistics hubs, this detector excels in diverse applications. In highway toll systems, its fast response prevents revenue loss from undetected vehicles, while warehouse door control benefits from its immunity to electromagnetic noise generated by forklifts or automated guided vehicles (AGVs). The universal 12-24V DC/100-240V AC input supports solar-powered and grid-connected installations, and the SPDT relay output (0.5A @ 120VAC) ensures seamless integration with traffic controllers, barriers, and IoT platforms. A recent deployment at a Middle Eastern port reduced gate congestion by 25% through precise truck detection and rapid gate cycling. Certified for CE and FCC, it also complies with RoHS environmental standards, making it a sustainable choice for modern infrastructure.

JUTAI’s detector stands out with plug-and-play installation and DIN-rail mounting, cutting setup time to under 20 minutes. The auto-reset function recovers automatically from power surges or transient faults, minimizing downtime. For parking management, its adjustable sensitivity eliminates false triggers from shopping carts or debris, and the 5-year warranty underscores its durability. Trusted globally in airports, smart cities, and industrial parks, the JUTAI High-Performance Detector redefines efficiency—where speed, precision, and ruggedness converge.

Features

• 1. 15-2000 μh detection Range
  • The loop detector supports a wide detection range from 15 µH to 2000 µH, accommodating various loop sizes and configurations for versatile application in different traffic detection scenarios. The wide detection range enables our loop detector to detect all kinds of vehicles, motorcycles, cars, Ultra long truck, buses and so on.

• 2. Compact Side
  • The compact and well-engineered housing combines all industry requirements for features and functionality, allowing this detector to be incorporated into any existing traffic detection system.

• 3. LED Diagnostic Capabilities
  • Comprehensive diagnostics capabilities enable accurate diagnosis of loop and installation problems and shows through LED, ensuring optimal performance and reducing downtime.

• 4. Selectable Presence Time
  • The output of the presence relay can be selected to limit a detect output to a fixed time (greater than 30 minutes) while a vehicle remains on the loop, providing flexibility in traffic management.

• 5. Loop Presence Time
  • Interference between adjacent loop detectors can be identified through integral indication and eliminated by adjusting the frequency setting, ensuring reliable operation.

• 6. Two Separate Output Relays
  • Presence Relay A: Provides presence output and can be extended for 0, 2, 5, 8, 10, 15, 20, or 30 seconds, programmable with external 10-way DIP switches.
  • Pulse Relay B: Programmable with external 10-way DIP switches, it offers presence, pulse on entry, pulse on exit, or failed output, enhancing detection flexibility.

• 7. 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.

• 8. 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.

• 9. 10 Dip Switch
  • 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.

• 10. 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.
