Industrial Dual Loop Detector For High Speed Door And Separation Control
Industrial Dual Loop Detector For High Speed Door And Separation Control
Product Overview

The industrial dual loop detector (models LD200/LD202) is a professional-grade automation core tailored for high-speed doors and industrial separation control scenarios. It integrates dual independent detection channels, precise direction judgment, and anti-interference performance, specifically adapting to the high-frequency opening/closing, fast vehicle flow, and strict safety requirements of industrial environments.

This detector not only realizes automatic triggering of high-speed doors but also achieves accurate separation control of personnel and vehicles, bidirectional traffic management, and anti-collision protection—making it essential equipment for warehouses, logistics parks, factories, and loading docks.

Core Functions & Product Advantages
  • High-Speed Door Intelligent Trigger Detects vehicles (cars, trucks, forklifts) in real-time, triggering high-speed doors to open quickly (response time 10-90 ms) and close automatically after passage, improving logistics throughput.
  • Dual-Channel Separation Control Works as two independent detectors or a coordinated system, separating entry/exit lanes, personnel/vehicle channels, or inbound/outbound goods flow to avoid cross-interference.
  • Bidirectional Direction Judgment 3 configurable modes accurately identify vehicle travel direction, supporting one-way passage control and two-way flow counting for industrial traffic management.
  • Anti-Collision & Safety Protection Continuously monitors vehicle presence during door operation; if a vehicle is detected in the passage, the door pauses closing to prevent collision and ensure personnel/equipment safety.
  • Industrial-Grade Stability Withstands -40°C~+70°C extreme temperatures, 95% non-condensing humidity, and industrial vibration, with dustproof and waterproof housing adapting to harsh workshop environments.
  • Anti-Interference Design 8-level adjustable sensitivity (0.015%-0.8% DL/L) and 4-step frequency (20-100 kHz) per channel, avoiding cross-talk with adjacent metal structures or electronic equipment.
  • Large Vehicle Adaptation DIP switch-enabled sensitivity boost prevents false door closure when trailers, heavy-duty trucks, or long cargo vehicles pass through.
  • Intuitive Fault Diagnostics LED indicators display power, detection status, and loop faults (short/open circuit), enabling quick troubleshooting and reducing downtime.

Sensitivity & Frequency Configuration
Industrial Dual Loop Detector For High Speed Door And Separation Control

Sensitivity and frequency adjustment is facilitated through 7-way 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 (0.8 to 0.015)
  • DIP switches 3, 4, and 5 control CH2 sensitivity (0.8 to 0.015)

Reset Button Note: The LD-200 must be reset every time a setting change is made to the DIP switches.
Installation Guidelines
Industrial Dual Loop Detector For High Speed Door And Separation Control Industrial Dual Loop Detector For High Speed Door And Separation Control
  • Coil cutting size should be a rectangle: 1.0-2.0m length × 0.8-1.2m width
  • Avoid right angles at corners as much as possible
  • Use ferromagnetic wires for induction coil (up to 500 meters total length)
  • Keep product plug and socket in vertical direction during installation
System Integration & Applications
Industrial Dual Loop Detector For High Speed Door And Separation Control
Working Principle
Entry Process
  1. Car enters community/parking lot, pressing both loop coils simultaneously
  2. LD-200/202 triggers UHF reader at entrance
  3. UHF reader reads card ID and sends to controller via Wiegand output
  4. Controller verifies ID validity and outputs relay signal to open gate barrier
  5. Car enters, barrier arm lowers automatically after passage
  6. LD-100/102 provides safety and anti-smashing functionality
Exit Process
  1. Car exits, passing by inside UHF reader
  2. LD-200/202 triggers UHF reader to read card and send ID to controller
  3. Controller verifies ID and opens gate barrier for exit
  4. Barrier arm lowers automatically after car passage
  5. LD-100/102 provides safety and anti-smashing functionality
Direction Recognition

The Direction Recognition Function ensures the double channel 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.

Industrial Dual Loop Detector For High Speed Door And Separation Control
Independent Operation Mode

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.

Industrial Dual Loop Detector For High Speed Door And Separation Control
Cost-Saving Benefit: By utilizing the LD-200/202 as two independent loop detectors, there is potential cost-saving from reduced hardware costs associated with using separate detectors for each function.
