Description
Dual Channel Parking Vehicle Detector with 20-100kHz Adjustable Frequency and 8 Sensitivity Levels
Dual Channel Parking Vehicle Detector with 20-100kHz Adjustable Frequency and 8 Sensitivity Levels
Eight Sensitivity Levels
Selectable sensitivity values from 0.015% (highest) to 0.8% (lowest). CH1 and CH2 can be independently adjusted according to loop conditions.
20-100kHz Frequency Adjustment
Four frequency groups: High, Medium-High, Medium-Low and Low. Helps minimize mutual interference between adjacent sensing systems.
Dual-Channel Functions
Six selectable working modes provide presence outputs, pulse outputs and directional behaviors for advanced entrance/exit logic.
Additional Functions
  • Approximately 10-minute automatic reset in normal mode
  • Permanent presence mode
  • Trailer sensitivity enhancement
  • Separate CH1 and CH2 detection LEDs
  • Loop open/short diagnostic indication
  • DIP-switch configuration with reset after setting changes

Best-Fit Applications
  • Multi-loop parking sites
  • Barrier gates with two detection zones
  • Adjacent parking lanes requiring frequency separation
  • Vehicle-access systems
  • Directional entrance/exit detection
  • Commercial and residential parking areas
Troubleshooting Value
The LED behavior assists commissioning. Slow flashing indicates a short circuit or insufficient loop turns, while faster flashing indicates an open loop or too many turns. Adjust frequency and correct loop turns as required.

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:

Reset Button Note: The LD-200 must be reset every time a setting change is made to the Dip switches.
Installation Guidelines
  • Coil cutting size should be rectangle: length 1.0 to 2.0 meters, width 0.8 to 1.2 meters
  • Avoid right angles at corners as much as possible
  • Use ferromagnetic wires for induction coil, total length up to 500 meters
  • Keep product plug and socket in vertical direction during installation

System Integration
The JUTAI LD200/202 double-channel vehicle loop detector series, equipped with direction recognition function, is ideal for single-channel entry and exit scenarios when integrated with:
  • JUTAI One door controller (Model: AC-11)
  • JUTAI gate barrier (Model: BR-110)
  • JUTAI long-range RFID reader (Model: PUHF-9)
  • High-temperature resistance loop coils (Model: JTHT-11)

Working Principle
Entry Process
  1. Car enters community/parking lot, pressing two loop coils simultaneously
  2. LD-200/202 triggers UHF reader at entrance
  3. UHF reader reads card ID and sends to controller via Wiegand output
  4. Controller verifies ID validity and outputs relay signal to open gate barrier
  5. Car enters, barrier arm lowers automatically
  6. LD-100/102 provides safety and anti-smashing functionality
Exit Process
  1. Car exits community/parking lot, passing inside UHF reader
  2. LD-200/LD-202 triggers UHF reader to read card and send ID to controller
  3. Controller verifies ID validity and outputs relay signal to open gate barrier
  4. Car exits, barrier arm lowers automatically
  5. LD-100/102 provides safety and anti-smashing functionality
Direction Recognition
The Direction Recognition Function ensures the double channels loop detector does not trigger the signal again when the car passes another UHF reader, recording only entry or exit records in the system.

Independent Operation Mode
The JUTAI LD-200/202 Double Channel Loop Detector can also function as two independent single-channel loop detectors, suitable for standard one-in and one-out parking lots. This configuration provides cost-saving benefits by reducing hardware costs.
