The loop sensor—alternatively called a vehicle loop detector or
traffic loop sensor—stands as a robust, all-purpose vehicle
detection solution engineered to elevate the efficiency of access
control systems and traffic management setups. Crafted to thrive in
both indoor and outdoor environments, this device offers precise
detection of cars, trucks, motorcycles, and commercial vehicles,
making it a go-to choice for diverse scenarios ranging from
residential gate access to busy highway traffic monitoring.
What sets this loop sensor apart is its adjustable frequency
feature, with a 4-step selectable range of 20–80 kHz. This allows
technicians to fine-tune the device to avoid signal interference
from nearby loops, metal infrastructure, or electronic
equipment—ensuring consistent performance even in crowded access
control points or high-traffic intersections. Complemented by a
rugged weatherproof housing (IP-rated for dust and water
resistance), it braves rain, snow, dust, and extreme temperatures
(-40°C to +70°C), delivering unwavering reliability in exposed
outdoor settings or harsh industrial access areas.
- Customizable Frequency for Anti-Interference: 4-step adjustable frequency (20–80 kHz) eliminates cross-talk
with adjacent devices, guaranteeing accurate detection in complex
access control and traffic environments.
- Weatherproof & Durable Construction: IP-rated housing shields internal components from the elements,
making it suitable for outdoor access gates, road intersections,
and exposed toll booths.
- Dual Relay Outputs for Flexibility: Presence Relay (for continuous vehicle monitoring) and
Pulse/Fault Relay (for trigger-based actions like gate activation
or traffic signal triggering) enable seamless integration with
diverse systems.
- Wide Sensitivity Range: 16-level adjustable sensitivity (0.010% to 2.56% DL/L) ensures
reliable detection of vehicles of all sizes, from lightweight
motorcycles to heavy-duty trucks.
- Easy Configuration & Maintenance: Intuitive DIP switches for delay settings, auto-reset, and
frequency adjustment, plus LED indicators (power and detection
status) and a manual reset button, simplify on-site setup and
troubleshooting.
- Dual Power Compatibility: Supports 100–240V AC (for permanent installations) and 12–24V DC
(for mobile or off-grid access control setups), adapting to varied
power requirements.
This versatile loop sensor excels in:
- Residential & Commercial Access Control: Gate automation for communities, office parks, and retail
centers, ensuring secure vehicle entry/exit.
- Traffic Signal Management: Intersection vehicle presence detection to optimize signal timing
and reduce congestion.
- Toll Collection & Checkpoints: Vehicle detection for automated toll booths, border checkpoints,
and security screening areas.
- Industrial Access Management: Factory and warehouse vehicle access control, preventing
unauthorized entry to restricted zones.
- Public Transit Facilities: Detection of buses, shuttles, and service vehicles at airports,
train stations, and bus terminals.
- Highway & Road Monitoring: Traffic flow counting, congestion detection, and data collection
for transportation planning.
- Parking Lot Systems: Entry/exit barrier control and occupancy monitoring for
commercial parking facilities, malls, and stadiums.
- Specialized Access Points: Vehicle detection for drive-throughs, car washes, and EV charging
stations.
Engineered for adaptability and durability, this loop sensor
combines adjustable frequency, weatherproof design, and flexible
integration to meet the demands of modern access control and
traffic management. It’s a reliable choice for facility managers,
traffic engineers, and security professionals seeking a
high-performance vehicle detection solution that delivers
consistent results in any environment. Backed by a 2-year warranty
and round-the-clock support, it’s an investment that ensures
long-term operational efficiency.
