LD-200 Double Channel Loop Sensor For Parking Barrier Access Vehicle Detector
Professional Dual Channel Vehicle Loop Detector

The JUTAI Dual Channels Traffic Detector (LD-200/202) is designed to detect vehicles and provide reliable traffic monitoring for parking access control systems.

Double Channel Car Parking Management Inductive Loop Detector
Key Features
Dual Channel Operation

Detects vehicles on two separate loops (CH1 and CH2) for comprehensive monitoring

Visual Indicators

Power LED (RED) indicates "Power ON", CH1 and CH2 Detection LEDs show vehicle detection and loop status

Adjustable Settings

Sensitivity and frequency adjustment via dip switches for customized operation

Multiple Operation Modes

Various modes for direction detection and normal operation with reset functionality

Technical Advantages
  • Compact Design: Well-engineered housing for easy integration into existing systems
  • Comprehensive Diagnostics: Accurate diagnosis of loop and installation problems
  • Selectable Presence Time: Output can be limited to fixed time while vehicle remains on loop
  • Frequency Management: Eliminate interference between adjacent loops with frequency settings
  • Direction Detection: CH1 to CH2 movement triggers CH1 relay; CH2 to CH1 triggers CH2 relay
  • Sensitivity Control: Adjustable via 7-way and 10-way dip switch settings
Professional 110-240VAC Double Channel Vehicle Loop Detector
Operation Modes

The LD-200 series detector may be configured for any one of the following modes:

  • Presence Mode
  • Pulse Mode
  • AB Logic Presence Mode (Barrier Operation)
  • AB Logic Pulse Mode (Counting Logic)
Multi-type voltage vehicle loop detection sensors

Indicator Functions
  • Power LED (RED): Indicates "Power ON"
  • CH1 Detecting LED:
    • Continuously On: Vehicle detection
    • Blinking slowly: Loop short circuit or insufficient twists
    • Blinking fast: Loop open circuit or excessive twists
  • CH2 Detecting LED:
    • Continuously On: Vehicle detection
    • Blinking slowly: Loop short circuit or insufficient twists
    • Blinking fast: Loop open circuit or excessive twists
Switch Configuration

Sensitivity and frequency adjustment is achieved through 7-way and 10-way dip switch settings:

Switch Configuration Diagram
Reset Requirement: The LD-200 must be reset every time a setting change is made to the Dip switches.
Installation Guidelines
  • Use ferromagnetic wires for induction coil (up to 500 meters total length)
  • Coil cutting size: Rectangle 1.0-2.0m length × 0.8-1.2m width
  • Avoid right angles at corners
  • Keep product plug and socket in vertical direction during installation
Coil Installation Overview Proper Installation Orientation
Working Principle
Entry Process Exit Process
  1. Both loop coils detect car entry
  2. LD-200/202 triggers UHF reader at entrance
  3. UHF reader sends ID to controller (AC-11)
  4. Controller outputs relay signal to open gate barrier
  5. Car enters and barrier lowers automatically
  6. LD-100/102 ensures safety and anti-smashing functionality
  1. Car passes inside UHF reader during exit
  2. LD-200/202 triggers UHF reader to read card ID
  3. Controller verifies ID validity and opens gate barrier
  4. Car exits as barrier arm lowers automatically
  5. LD-100/102 provides safety and anti-smashing functionality
Troubleshooting Guide
Symptoms Solution
Detector not working Press reset button
Red LED indicator not fully lit Check power supply
Green LED blinking slowly Loop short circuit or insufficient turns - lower frequency or add turns
Green LED blinking faster Loop open circuit or excessive turns - higher frequency or remove turns
