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. The
integrated short/open circuit indicator (via LED signals) instantly
alerts maintenance teams to loop wiring issues, eliminating
time-consuming troubleshooting and ensuring uninterrupted access
flow.
- 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.
This gate loop detector is tailored for:
- 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.
