Loop Detector Single And Dual Channel Models For Vehicle Presence Pulse

JUTAI single and dual channel loop detectors are professional-grade solutions engineered for accurate vehicle presence sensing and pulse detection, ideal for access control, gate automation, and traffic management scenarios. With industrial-grade build quality and flexible configuration, these detectors seamlessly adapt to indoor/outdoor installations while supporting seamless integration with gate controllers, traffic counters, and access systems.

Our product lineup covers two core series to meet diverse needs:

• Single Channel (LD100 AC / LD102 DC): Specialized for basic vehicle presence detection and pulse-triggered actions, perfect for simple gate and industrial door automation.
• Dual Channel (LD200 AC / LD202 DC): Equipped with advanced directional sensing and traffic counting capabilities, designed for entry/exit management, toll plazas, and dual-zone monitoring.

All detectors ensure reliable identification of cars, trucks, motorcycles, forklifts, and other vehicles, delivering consistent performance in harsh environmental conditions.

• 15+ years of specialized experience in vehicle detection technology, with a focus on presence and pulse detection reliability.
• Comprehensive product range from basic single-channel solutions to advanced dual-channel systems for complex scenarios.
• Strict quality control and full pre-shipment testing to ensure long-term performance in high-demand environments.
• Support for OEM/ODM customization and standard orders, tailored to specific project requirements.
• All products backed by a 2-year warranty and dedicated technical support for seamless deployment.

• Choose Single Channel detectors for straightforward vehicle presence sensing and pulse-triggered automation (e.g., gate opening/closing).
• Choose Dual Channel detectors for directional judgment, traffic counting, or dual-zone presence/pulse detection (e.g., entry/exit management).

• 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).

1. Coil Cutting Size and Embedding Guidelines are as shown in the diagram on the right.
2. It is recommended to use ferromagnetic wires for the induction coil, with a total length of up to 500 meters.
3. 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.
4. Recommended installation overview of basic typical coil turns:

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.

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.
