Dual Channel Loop Detector

Our dual channel loop detector is a microprocessor-based device designed specifically for parking and vehicle access control applications. It detects vehicle presence by sensing inductance changes caused by a vehicle passing over a wire loop buried beneath the road surface. This detector is versatile, offering multiple operating modes, including presence (fail-secure), pulse, and direction logic.

Key Features:

  • High Sensitivity and Stability: The dual channel loop detector provides reliable performance with a coil inductance range of 20-2000 μH. It consistently detects vehicles with precision, ensuring stable operation.
  • Versatile Output Relays: The output relays can be configured to operate in presence, pulse, or direction logic modes, catering to various traffic management needs.
  • Adjustable Sensitivity: The detector features 16 levels of sensitivity adjustment, allowing for fine-tuning to match specific operational requirements.
  • Durability in Extreme Conditions: Tested in high-temperature environments, our dual channel loop detector maintains efficient and normal operation, showcasing its robustness.

Our dual channel loop detector is designed with user-friendly interfaces and offers a stable working performance, making it an ideal solution for modern traffic management and vehicle access control systems. With its reliable detection capabilities and versatile functionality, this detector ensures smooth and efficient traffic flow management.

Key Features of the Dual Channel Loop Detector

Our dual channel loop detector offers advanced functionality designed to enhance traffic management systems, including:

  • Automatic Fault Detection: The detector automatically identifies and alerts you to any coil faults, ensuring reliable performance.
  • Adjustable Presence Output Time: The presence output time can be easily adjusted to suit various operational requirements.
  • Wireless Compatibility: Seamlessly integrates with our wireless controller system for enhanced flexibility and control.


  • Parking Lot Entrance Detection: Efficiently detects vehicles entering and exiting parking facilities.
  • Electronic Police Traffic Light Systems: Integrates with traffic light systems for accurate vehicle detection and snapshot capabilities.

Operating Features:

  • Configurable Working Modes: The vehicle loop detector's working mode can be set using a DIP switch, allowing for customized operation.
  • Adjustable Working Frequency: Frequency settings can be adjusted with two switches, primarily influenced by the coil geometry. The operational frequency range is 20-200 kHz.
  • Automatic Sensitivity Adjustment: The dual channel traffic detector  includes an automatic sensitivity upgrade feature, activated via switches, to maintain optimal detection performance.
  • Pulse Relay Modes: Supports leave pulse and enter pulse working modes, providing versatile application options.
  • Fast Response Time: The detector boasts a quick response time of 20 milliseconds, ensuring timely vehicle detection.
  • Drift Compensation: Features timely drift compensation to maintain accuracy in varying conditions.
  • Wide Operating Temperature Range: Designed to function efficiently in temperatures ranging from -20°C to 60°C.

Key Benefits:

  • Accident Prevention: Ensures safety by preventing gates from operating unexpectedly during power outages or resets.
  • Advanced Technology: Utilizes a cutting-edge micro-controller for precise and reliable vehicle detection.
  • Wide Application: Suitable for industrial, commercial, and residential gate operators, helping to manage heavy gates and vehicle barricades effectively.

Enhanced Functionality:

  • Hold-Open Feature: Typical dual channel loop detectors keep the gate open until the last part of a vehicle has passed the closing loop, which is located beyond the gate. The detector then issues a departure pulse, instructing the gate to close after the vehicle has fully passed.
  • Seamless Integration: Compatible with various gate operator systems, ensuring smooth operation and enhanced safety.

Additional Features:

  • Quality Assurance: We offer a sample set for quality evaluation, allowing you to verify our product's high standards.
  • Reasonable Pricing: Our dual channel loop detectors are priced competitively and include fast delivery options.
  • OEM Services: We accept OEM requests, providing customizable solutions to meet specific needs.
