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:
- 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. Eight different sensitivity settings available via dip switch configuration.

Switch Configuration

Switch 1 (S1) - Channel 1 Loop Function Selection:

DIP 1 & DIP 2: Special Sensitivity Increase For Both Trailer (Both Channels)
D3, D4, D5 and Switch 2 D1, D2: Special Functions (Mode1, 2, 3 Direction Detection. Mode 4, 5, 6 Normal mode)
D6 & D7 & D8 and Switch 2 D3 & D4 & D5: CH1 and CH2 Sensitivity Selection (Eight Levels)
D9 & D10 and Switch2 D6, D7: Frequency Selection (20 K to 100 KHz)

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

Car enters community/parking lot, pressing two loop coils simultaneously
LD-200/202 triggers UHF reader at entrance
UHF reader reads card ID and sends to controller via Wiegand output
Controller verifies ID validity and outputs relay signal to open gate barrier
Car enters, barrier arm lowers automatically
LD-100/102 provides safety and anti-smashing functionality

Exit Process

Car exits community/parking lot, passing inside UHF reader
LD-200/LD-202 triggers UHF reader to read card and send ID to controller
Controller verifies ID validity and outputs relay signal to open gate barrier
Car exits, barrier arm lowers automatically
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.
