JUTAI single/dual channel vehicle loop detectors feature adjustable sensitivity, industrial-grade reliability, and seamless integration—tailored for parking gate automation and traffic system management.

Our product line covers:

• Single Channel (LD100 AC/LD102 DC): Basic presence/pulse detection for gates/industrial doors
• Dual Channel (LD200 AC/LD202 DC): Advanced directional sensing + traffic counting for entry/exit systems

All models deliver accurate detection of cars, trucks, motorcycles, and forklifts, with robust performance for indoor/outdoor installations.

• Precision Adjustable Sensitivity: Single Channel models offer 16-level sensitivity adjustment; Dual Channel models provide 8-level independent sensitivity per channel
• Configurable Operating Modes: Supports presence, pulse, and auto-reset modes; Dual Channel variants add 3 specialized direction detection modes
• Real-Time Status Monitoring: LED indicators for power, detection status, and fault alerts enable quick troubleshooting
• Industrial-Grade Durability: Weatherproof housing and wide operating temperature range (-40°C to +70°C)
• Easy Integration & Configuration: Manual reset button for configuration changes, compatible with standard parking gate controllers
• Anti-Interference Design: 4-step selectable frequency avoids cross-talk with adjacent loops

• Single Channel Use Cases: Parking gate automation, industrial roller door activation, warehouse forklift detection, security boom gate control
• Dual Channel Use Cases: Parking gate entry/exit counting systems, traffic system flow monitoring, toll booth vehicle classification, dual-lane parking gate management

• Over 15 years of specialization in vehicle detection technology
• Complete product range from basic to advanced solutions
• Rigorous quality control and full pre-shipment testing
• Adjustable sensitivity tailored to parking gate and traffic system needs
• All products backed by a 2-year warranty and expert technical support

• Choose Single Channel detectors for parking gate automation, single-lane access control, or basic vehicle presence detection
• Choose Dual Channel detectors for traffic system counting, parking gate entry/exit management, directional sensing, or dual-lane detection scenarios

• Power LED (RED): Illuminates to indicate "Power ON"
• CH1 Detection LED:
  • Steady On: Vehicle detection
  • Slow Blinking: Loop short circuit or insufficient twists
  • Fast Blinking: Loop open circuit or excessive twists
• CH2 Detection LED:
  • Steady On: Vehicle detection
  • Slow Blinking: Loop short circuit or insufficient twists
  • Fast Blinking: Loop open circuit or excessive twists

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.

• Use ferromagnetic wires for the induction coil, with total length up to 500 meters
• Coil cutting size should be rectangle: length 1.0-2.0m, width 0.8-1.2m
• Avoid right angles at corners as much as possible

The Direction Recognition Function 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.
