The loop detector—equipped with dual relay outputs and DIP switch
configurability—is a precision-engineered vehicle detection
solution tailored for toll booths and parking systems. Designed to
meet the high-demand, high-traffic needs of these scenarios, this
professional-grade device reliably detects cars, trucks, commercial
vehicles, and motorcycles, enabling seamless integration with toll
collection platforms, parking barriers, access control systems, and
occupancy monitoring tools.
What sets this loop detector apart is its dual relay output design
(Presence Relay + Pulse/Fault Relay) and intuitive DIP switch
configuration, allowing technicians to customize delay times,
frequency settings, auto-reset functions, and operational modes
without complex programming. Whether deployed in busy toll booths
for vehicle counting and toll trigger actions, or in parking
systems for entry/exit control and space occupancy monitoring, it
adapts to diverse workflow requirements with consistent accuracy.
Its rugged construction and wide environmental tolerance ensure
stable performance in both indoor parking facilities and exposed
toll plaza environments.
- Dual Relay Outputs: Independent Presence Relay (for continuous vehicle monitoring)
and Pulse/Fault Relay (for one-time triggers like toll calculation
or barrier lifting) enable flexible integration with toll and
parking automation systems.
- DIP Switch Configurability: Easy-to-access DIP switches for adjusting detection delay,
auto-reset, frequency (20–80 kHz), and sensitivity, allowing quick
calibration to suit toll booth traffic flow or parking lot layout.
- Toll & Parking Optimized Detection: Advanced sensing algorithm minimizes false triggers from adjacent
vehicles or metal structures, ensuring reliable detection even in
high-density toll lanes or crowded parking lots.
- Wide Vehicle Compatibility: 16-level adjustable sensitivity (0.010% to 2.56% DL/L) detects
vehicles of all sizes—from compact cars to heavy-duty
trucks—critical for mixed-traffic toll booths and parking
facilities.
- Dual Power Options: Supports 100–240V AC (LD100) for permanent installations (toll
plazas, parking garages) and 12–24V DC (LD102) for mobile or
off-grid setups, enhancing deployment flexibility.
- Durable & Weatherproof: IP-rated housing resists rain, dust, extreme temperatures (-40°C
to +70°C), and humidity up to 95% (non-condensing), suitable for
indoor/outdoor toll and parking environments.
This loop detector is ideal for:
- Toll Booth Operations: Vehicle detection for toll collection triggering, lane occupancy
monitoring, vehicle counting, and toll plaza traffic flow
management.
- Parking Garage Entry/Exit: Barrier gate activation, parking space occupancy detection, and
access control for commercial/residential parking garages.
- Open-Air Parking Lots: Vehicle counting, entry/exit barrier control, and real-time
occupancy monitoring for malls, stadiums, and public parking areas.
- Highway Toll Plazas: Mixed-traffic detection (cars, trucks, buses) for automated toll
calculation and lane management.
- Valet Parking Services: Vehicle presence detection for valet stand activation and parking
space allocation.
- Parking Guidance Systems: Individual parking space occupancy sensing to feed real-time
availability data to guidance displays.
- Drive-Through Toll Lanes: Fast-response vehicle detection for contactless toll collection
systems.
- Airport/Port Parking: Heavy-duty vehicle detection for cargo trucks and passenger
vehicles in high-traffic transportation hubs.
Engineered to streamline toll booth and parking system operations,
this dual relay output, DIP switch-configurable loop detector
balances precision, flexibility, and durability. It’s the preferred
choice for transportation authorities, parking facility managers,
and toll system integrators seeking a reliable, easy-to-configure
detection solution that minimizes downtime and maximizes
operational efficiency. Backed by a 2-year warranty and
round-the-clock technical support, it’s a long-term investment for
high-performance toll and parking management.
