Single & Dual Channel Vehicle Loop Detector: Adjustable Sensitivity For Parking Gate & Traffic Systems
Single Dual Channel Vehicle Loop Detector Adjustable Sensitivity For Parking Gate Traffic System
Product Overview

JUTAI single/dual channel vehicle loop detectors feature adjustable sensitivity, industrial-grade reliability, and seamless integration—tailored for parking gate automation and traffic system management.

Our product line covers:

  • Single Channel (LD100 AC/LD102 DC): Basic presence/pulse detection for gates/industrial doors
  • Dual Channel (LD200 AC/LD202 DC): Advanced directional sensing + traffic counting for entry/exit systems

All models deliver accurate detection of cars, trucks, motorcycles, and forklifts, with robust performance for indoor/outdoor installations.

Key Features
  • Precision Adjustable Sensitivity: Single Channel models offer 16-level sensitivity adjustment; Dual Channel models provide 8-level independent sensitivity per channel
  • Configurable Operating Modes: Supports presence, pulse, and auto-reset modes; Dual Channel variants add 3 specialized direction detection modes
  • Real-Time Status Monitoring: LED indicators for power, detection status, and fault alerts enable quick troubleshooting
  • Industrial-Grade Durability: Weatherproof housing and wide operating temperature range (-40°C to +70°C)
  • Easy Integration & Configuration: Manual reset button for configuration changes, compatible with standard parking gate controllers
  • Anti-Interference Design: 4-step selectable frequency avoids cross-talk with adjacent loops

Indicators and Switches
  • Power LED (RED): Illuminates to indicate "Power ON"
  • CH1 Detection LED:
    • Steady On: Vehicle detection
    • Slow Blinking: Loop short circuit or insufficient twists
    • Fast Blinking: Loop open circuit or excessive twists
  • CH2 Detection LED:
    • Steady On: Vehicle detection
    • Slow Blinking: Loop short circuit or insufficient twists
    • Fast Blinking: Loop open circuit or excessive twists
Sensitivity Selection

Sensitivity and frequency adjustment is facilitated through 7-way and 10-way dip switch settings. Users can choose from 8 different sensitivity settings by configuring the dip switch positions.

Reset Button Note: The LD-200 must be reset every time a setting change is made to the Dip switches.
Installation Precautions
  • Use ferromagnetic wires for the induction coil, with total length up to 500 meters
  • Coil cutting size should be rectangle: length 1.0-2.0m, width 0.8-1.2m
  • Avoid right angles at corners as much as possible

Application & Working Principle
Single Dual Channel Vehicle Loop Detector Adjustable Sensitivity For Parking Gate Traffic System
Entry Process
1. Car enters and presses two loop coils simultaneously
2. Loop Detector triggers UHF reader at entrance
3. UHF reader reads card ID and sends to controller
4. Controller verifies ID validity and opens gate barrier
5. Car enters and barrier arm lowers automatically
6. Single Channel Loop Detector ensures safety and anti-smashing functionality
Exit Process
1. Car passes by inside UHF reader
2. Loop Detector triggers UHF reader to read card
3. Controller verifies ID and opens gate barrier
4. Car exits and barrier arm lowers automatically
5. Single Channel Loop Detector provides safety and anti-smashing functionality
Direction Recognition

The Direction Recognition Function ensures that the double channels loop detector does not trigger the signal again when the car passes another UHF reader, thereby recording only the entry or exit records in the system.
