Single & Dual Channel Vehicle Detector For Car Park Barrier Gate And Counting System
Product Overview
JUTAI single and dual channel vehicle detectors are specialized solutions for car park barrier gate automation and occupancy counting systems, delivering precise vehicle detection, reliable trigger control, and accurate traffic data collection. Built with industrial-grade durability, they seamlessly integrate with barrier gate controllers and counting platforms, adapting to indoor/outdoor car parks of all sizes.
Our product range targets core car park needs:
Single Channel (LD100 AC / LD102 DC): Optimized for basic barrier gate activation and single-point presence detection, ideal for small to medium-sized car parks.
Dual Channel (LD200 AC / LD202 DC): Equipped with directional sensing and dual-zone monitoring, designed for car park entry/exit counting and bidirectional barrier gate management.
All detectors ensure consistent identification of cars, motorcycles, SUVs, and light commercial vehicles, minimizing false triggers and maximizing operational efficiency.
Key Features
Barrier Gate Trigger Precision: Supports pulse output (one-time barrier lifting) and presence hold (keeps barrier open during vehicle passage), with 10-90 ms response time to avoid collisions.
Accurate Counting Capability (Dual Channel Exclusive): 3 configurable direction modes distinguish entry/exit traffic, eliminating duplicate or missed counts for real-time occupancy data.
Adjustable Sensitivity: Single Channel (16-level tuning); Dual Channel (8-level independent adjustment per channel) - adapts to different vehicle sizes and avoids false triggers from metal debris.
Industrial-Grade Reliability: Weatherproof housing, -40°C~+70°C operating temperature range, and 95% non-condensing humidity tolerance - suitable for outdoor car park environments.
Real-Time Status Monitoring: LED indicators display power, detection status, and loop faults (short/open circuit), enabling quick troubleshooting to reduce downtime.
Anti-Interference Design: 4-step selectable frequency (20-80 kHz for Single Channel; 20-100 kHz for Dual Channel) eliminates cross-talk with adjacent loops or car park equipment.
Easy Integration: Dual relay outputs connect seamlessly with barrier gate controllers, counting displays, and car park management software - no complex programming required.

Technical Details & Configuration
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 after the loop.
Fast Blinking: Indicates a loop open circuit or excessive twists after the loop.
CH2 Detection LED:
Steady On: Indicates vehicle detection.
Slow Blinking: Indicates a loop short circuit or insufficient twists after the loop.
Fast Blinking: Indicates a loop open circuit or excessive twists after the loop.
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 according to the provided tables.
Dip switches 6, 7, and 8 govern CH1 sensitivity, ranging from 0.8 (least sensitive) to 0.015 (most sensitive).
Dip switches 3, 4, and 5 control CH2 sensitivity, ranging from 0.8 (least sensitive) to 0.015 (most sensitive).
Reset Button: Please note: 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 on the right.
It is 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, avoiding right angles at corners as much as possible.
When installation, please keep the product plug and socket in the vertical direction.
System Integration & Working Principle
Working Principle:
Entry Process:
When a car enters the community or parking lot, the two loop coils are pressed simultaneously.
The JUTAI Double Channel Loop Detector (LD-200/202) triggers the UHF reader located at the entrance.
The UHF reader reads the card ID and sends it to the controller (AC-11) via Wiegand output.
The controller verifies the ID's validity and outputs a relay signal to open the gate barrier.
The car enters the community or parking lot, and as it passes the barrier gate, the barrier arm lowers automatically.
The JUTAI Single Channel Loop Detector (LD-100/102) ensures safety and anti-smashing functionality during this process.
Exit Process:
When a car exits the community or parking lot, it passes by an inside UHF reader.
The LD-200/LD-202 triggers the UHF reader, which reads the card and sends the ID to the controller.
The controller verifies the ID's validity and outputs a relay signal to open the gate barrier for the car to exit.
As the car passes through the barrier gate, the barrier arm lowers automatically.
The LD-100/102 provides safety and anti-smashing functionality during this process.
Direction Recognition:
The Direction Recognition Function of LD-200/LD-202 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.
The JUTAI LD-200/202 Double Channel Loop Detector can also function as two independent single-channel loop detectors. This configuration is suitable for standard one-in and one-out parking lots, where there is one barrier and one long-range reader at both the entrance and exit.
In this setup, one loop coil is used to trigger the reader and read the card, while the other loop coil is dedicated to the barrier's anti-smashing function. By utilizing the LD-200/202 as two independent loop detectors, there is a potential cost-saving benefit from an economic standpoint.
