Industrial Loop Detector for Forklift Truck Detection 12-24V DC
100-240V AC Relay Output

Designed specifically for industrial environments, the industrial
loop detector (also known as a forklift loop sensor) is a
high-reliability vehicle detection solution tailored to identify
forklifts, heavy-duty trucks, and industrial vehicles with
unmatched accuracy. Whether deployed in warehouses, logistics
centers, loading docks, or manufacturing plants, this versatile
device supports both 12-24V DC and 100-240V AC power inputs, paired
with dual relay outputs (Presence + Pulse/Fault) to seamlessly
integrate with industrial automation, access control, and safety
systems.
Crafted to withstand the rigors of industrial operations, the
forklift loop detector works with embedded inductive loops to
detect vehicles of all sizes—from compact forklifts to large cargo
trucks—without false triggers. It features 16 levels of adjustable
sensitivity (0.010% to 2.56% DL/L) and a 4-step selectable
frequency range (20-80 kHz), allowing precise calibration to suit
different loop configurations, floor materials, and vehicle
weights. The device's rugged, weatherproof housing ensures stable
performance in extreme industrial conditions, with an operating
temperature range of -40°C to +70°C and resistance to humidity up
to 95% (non-condensing).
Core Features of Industrial Forklift Loop Detector
- Specialized Industrial Vehicle Detection: Optimized for forklifts, cargo trucks, and heavy-duty industrial
vehicles, ensuring reliable sensing even in high-traffic warehouse
or logistics environments.
- Dual Power Compatibility: Supports 12-24V DC (ideal for mobile or off-grid setups) and
100-240V AC (for permanent industrial installations), offering
flexible deployment options.
- Dual Relay Outputs: Presence Relay for continuous vehicle monitoring (e.g., loading
dock occupancy) and Pulse/Fault Relay for trigger actions (e.g.,
door activation, alarm triggers), enhancing system integration.
- Precision Tuning: 16-level adjustable sensitivity and selectable frequency range
eliminate interference from metal structures, machinery, or
adjacent loops, ensuring accurate detection.
- Industrial-Grade Durability: Weatherproof housing and wide temperature/humidity tolerance make
it suitable for indoor and outdoor industrial use, from cold
storage facilities to outdoor loading yards.
