Vehicle Detection Sensor Single Channel For Gate Dual Channel For Direction Counting

JUTAI vehicle detection sensors offer targeted solutions for access control and traffic management, with single-channel models optimized for gate automation and dual-channel variants engineered for directional sensing and traffic counting. Built with industrial-grade precision and rugged durability, these sensors deliver reliable performance for indoor/outdoor applications, including parking lots, industrial facilities, residential complexes, and toll plazas.

All sensors support seamless integration with gate controllers, traffic counters, and access control platforms, with weatherproof housing and wide temperature tolerance to adapt to harsh environmental conditions.

• Gate-optimized Trigger Modes: Supports pulse output (one-time gate lifting) and presence hold (keeps gate open during vehicle passage), with 10-90 ms response time to avoid collisions.
• 16-level Adjustable Sensitivity: Fine-tune detection precision to match vehicle sizes (from motorcycles to SUVs) and eliminate false triggers from metal debris or adjacent structures.
• Easy Configuration: DIP switch control for sensitivity and operating modes, no complex software required—enables quick on-site setup for gate systems.
• Industrial-grade Reliability: -40°C to +70°C operating temperature range and 95% non-condensing humidity tolerance, suitable for outdoor gate installations.

• 3 Configurable Direction Modes: Accurately identifies vehicle travel direction (CH1→CH2 or CH2→CH1) to support entry/exit counting and bidirectional traffic flow analysis.
• Independent 8-level Sensitivity per Channel: Adjust each detection zone's sensitivity separately to adapt to different lane conditions and vehicle types.
• Anti-interference Design: 4-step selectable frequency (20-100 kHz) eliminates cross-talk between adjacent channels or loops, ensuring counting accuracy in high-traffic areas.
• Real-time Counting Compatibility: Seamlessly integrates with traffic counting displays and management software to provide real-time occupancy data for parking lots or roadways.

• Weatherproof Housing: Sealed, rugged housing protects against water, dust, and corrosion, ideal for outdoor deployments.
• Real-time Status Monitoring: LED indicators for power, detection status, and loop faults (short/open circuit) enable rapid troubleshooting.
• Flexible Power Options: Supports 100-240V AC for permanent installations and 12-24V DC for temporary setups (e.g., construction site gates).
• Dual Relay Outputs: Ensures reliable connection with gate controllers, traffic counters, and other automation equipment.

• 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 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).

• 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.

The JUTAI LD200/202 double-channel vehicle loop detector series, equipped with direction recognition function, is ideal for numerous single-channel entry and exit scenarios. When integrated with the JUTAI One door controller (Model: AC-11), JUTAI gate barrier (Model: BR-110), and JUTAI long-range RFID reader (Model: PUHF-9), along with high-temperature resistance loop coils (Model: JTHT-11), it forms a seamless solution for single-channel entry/exit access control systems.

• 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.

• 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.

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. This setup reduces some of the hardware costs associated with using separate detectors for each function.

This functionality is achieved by enabling the Independent Working Mode feature of the LD-200/202, allowing it to operate effectively in this dual capacity.
