Gate Loop Detector for Barrier Industrial Doors Loop Short Open Circuit Indicator Reliable Performance

Gate Loop Detector for Barrier Industrial Doors Loop Short Open Circuit Indicator Reliable Performance
Gate Loop Detector for barrier gates and industrial doors
Gate Loop Detector for Barrier & Industrial Doors

The gate loop detector—specialized for barrier gates and industrial doors—is a high-reliability vehicle detection solution engineered to ensure seamless automation, safety, and operational stability in commercial, industrial, and residential access scenarios. Designed to work with inductive loops embedded in driveways or entry points, this detector excels at identifying vehicles to trigger barrier lifting, industrial door opening, or access control actions—while its built-in short/open circuit indicator provides real-time fault diagnosis, minimizing downtime and simplifying maintenance.

Crafted for demanding access control environments, the detector delivers consistent performance even in high-traffic areas or harsh industrial conditions. Its rugged construction withstands vibration, dust, moisture, and extreme temperatures (-40°C to +70°C), making it ideal for heavy-duty industrial doors (such as high-speed roller doors, sectional doors) and barrier gates at warehouses, factories, parking lots, and logistics centers.

Core Features
  • Short/Open Circuit Indication: Dedicated LED indicators for loop short circuits and open circuits, enabling quick fault identification and reduced maintenance time.
  • Reliable Vehicle Detection: Optimized sensing algorithm detects cars, trucks, forklifts, and commercial vehicles with minimal false triggers, ensuring precise barrier/door activation.
  • Industrial-Grade Durability: Rugged housing resistant to dust, moisture, vibration, and extreme temperatures, tailored for industrial door and barrier gate environments.
  • Dual Operational Modes: Presence Mode (for continuous vehicle monitoring to hold doors open) and Pulse Mode (for one-time trigger actions like barrier lifting), adapting to diverse access needs.
  • Flexible Integration: Supports 100-240V AC (LD100) and 12-24V DC (LD102) power inputs, with dual relay outputs (SPDT) for seamless connection to gate controllers and industrial door automation systems.
  • Adjustable Sensitivity & Frequency: 16-level sensitivity (0.010% to 2.56% DL/L) and 4-step selectable frequency (20-80 kHz) to avoid interference from adjacent loops or metal structures.
