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.

• 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.

• Barrier Gate Systems: Parking lot entry/exit barriers, residential/commercial access barriers, and toll booth barrier activation.
• Industrial Door Automation: High-speed roller doors, sectional doors, and overhead doors in warehouses, factories, and logistics centers.
• Warehouse & Loading Docks: Forklift and truck detection to trigger loading dock door opening and safety interlocks.
• Commercial Access Control: Office park, mall, and stadium gate automation for vehicle entry/exit.
• Logistics & Distribution Centers: Heavy-duty vehicle detection for yard access control and internal traffic flow management.
• Residential Gated Communities: Automated gate activation with reliable vehicle sensing and fault monitoring.
• Industrial Plant Access: Restricted area access control for factory vehicles, with quick fault diagnosis via circuit indicators.

Built to prioritize reliability and ease of maintenance, this gate loop detector is the trusted choice for facility managers and industrial automation professionals. Its short/open circuit indicator, rugged design, and flexible integration ensure smooth operation of barrier gates and industrial doors—reducing downtime, enhancing safety, and optimizing access control efficiency. Backed by a 2-year warranty and 24/7 technical support, it's a long-lasting solution for demanding industrial and commercial access scenarios.
