JUTAI professional single and dual channel loop detectors are industrial-grade vehicle detection solutions backed by a 2-year warranty and dedicated technical support. Engineered for universal compatibility with cars, trucks, motorcycles, forklifts, and other vehicle types, these detectors combine adjustable sensitivity, rugged durability, and flexible configuration to deliver accurate detection across diverse industrial, commercial, and parking scenarios.
Product Lineup:
Single Channel Loop Detectors (LD100 AC / LD102 DC): Ideal for single-point vehicle detection, compatible with all common vehicle types for gate automation, industrial door activation, and basic access control.
Dual Channel Loop Detectors (LD200 AC / LD202 DC): Equipped with directional sensing and dual-zone monitoring, universally compatible with various vehicles for entry/exit counting, traffic flow analysis, and multi-lane access control.
Key Features
Adjustable Sensitivity for Multi-Vehicle Adaptation: Single channel models offer 16-level sensitivity tuning; dual channel models provide 8-level independent adjustment per channel.
Universal Vehicle Detection Algorithm: Optimized detection logic specifically calibrated for cars, trucks, motorcycles, and forklifts.
Dual Channel Directional Sensing (Dual Channel Exclusive): 3 configurable direction modes accurately identify travel direction of all vehicle types.
Industrial-Grade Durability: Weatherproof and dustproof housing, -40°C to +70°C operating temperature range, and 95% non-condensing humidity tolerance.
Anti-Interference Design: 4-step selectable frequency eliminates cross-talk with adjacent loops or industrial equipment.
Easy Configuration & Integration: DIP switch control for sensitivity, operating modes, and frequency; manual reset button for quick setup.
Real-Time Status Monitoring: LED indicators for power, detection status, and loop faults.

Installation Note: For mixed-vehicle scenarios, select loop perimeter based on the largest vehicle type; adjust sensitivity via DIP switches to ensure detection of smaller vehicles. Seal loop wires with quick-set epoxy to withstand traffic from heavy trucks and forklifts. For dual-channel direction detection, install loops 1m apart along the travel path.
Ideal Applications
Single Channel Use Cases
Industrial workshop gate automation (compatible with forklifts and employee cars)
Mixed-vehicle parking lot barrier gate control (cars, motorcycles, small trucks)
Loading dock door activation (forklifts, delivery trucks)
Residential complex access control (various private vehicles)
Dual Channel Use Cases
Industrial park entry/exit counting (forklifts, trucks, staff cars)
Logistics center traffic flow analysis (delivery trucks, forklifts)
Commercial parking lot bidirectional management (mixed cars, motorcycles, SUVs)
Construction site vehicle access control (heavy trucks, construction vehicles, staff cars)

Connections & Indicators
Indicators and Switches:
Power LED (RED): Illuminates to indicate "Power ON."
CH1 Detection LED:
Steady On: Indicates vehicle detection
Slow Blinking: Indicates a loop short circuit or insufficient twists
Fast Blinking: Indicates a loop open circuit or excessive twists
CH2 Detection LED:
Steady On: Indicates vehicle detection
Slow Blinking: Indicates a loop short circuit or insufficient twists
Fast Blinking: Indicates a loop open circuit or excessive twists
Sensitivity Selection:
Sensitivity and frequency adjustment is facilitated through a 7-way dip switch and 10-way dip switch settings. Users can choose from 8 different sensitivity settings by configuring the dip switch positions.
Reset Button: The LD-200 must be reset every time a setting change is made to the Dip switches.
Installation Guidelines
Coil Cutting Size and Embedding Guidelines are as shown in the diagram
Recommended to use ferromagnetic wires for the induction coil, with a total length of up to 500 meters
The cutting size of the coil should be a rectangle with a length of 1.0 to 2.0 meters and a width of 0.8 to 1.2 meters
Avoid right angles at corners as much as possible
System Integration & Applications
Working Principle
Entry Process:
Car enters and presses both loop coils simultaneously
Loop detector triggers UHF reader at entrance
Reader sends card ID to controller via Wiegand output
Controller verifies ID validity and opens gate barrier
Single channel detector ensures safety and anti-smashing functionality
Exit Process:
Car passes inside UHF reader when exiting
Loop detector triggers reader to read card and send ID to controller
Controller verifies ID and opens gate barrier
Single channel detector provides safety during exit process
Direction Recognition: Ensures detector doesn't trigger signal again when car passes another reader, recording only entry or exit records.
