Reliable Single Channel Detector - LED Status Indicators & Anti-crosstalk

The JUTAI Loop Detector series is engineered to deliver reliable, high-precision vehicle detection for diverse industrial and urban applications. Designed with 16-level sensitivity adjustment (0-F), these detectors adapt seamlessly to detect vehicles ranging from motorcycles to heavy-duty trucks (20–2000μH inductance range). The frequency customization (40–80KHz) eliminates cross-talk interference in multi-detector setups, ensuring stable performance in complex environments like toll plazas, parking garages, or logistics hubs. Built for durability, the IP67-rated housing protects against dust, water ingress, and extreme temperatures (-40°C to +70°C), making it ideal for both indoor and outdoor installations.

Single-Channel Models (LD-100/LD-102):

• LD-100: Operates on 100–240V AC, perfect for grid-connected parking systems or traffic lights.
• LD-102: Supports 12–24V DC, ideal for solar-powered gates or industrial door control.
  Both models feature dual relay outputs (pulse + presence detection) with configurable delay settings (0–30s) for precise barrier or signal control.

Dual-Channel Models (LD-200/LD-202):

• Channel 1: Triggers gates/traffic signals with ≤10ms response.
• Channel 2: Provides safety redundancy for anti-collision or toll evasion prevention.
  The auto-reset function ensures uninterrupted operation during power fluctuations, while LED indicators simplify fault diagnosis (coil shorts, open circuits).

Certified for CE, FCC, and RoHS, JUTAI detectors are trusted globally in smart cities, warehouses, and highways. With plug-and-play installation and DIN-rail compatibility, they minimize downtime and maintenance costs—proving that robust performance doesn’t require complexity.

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.
