Inductive Loop Detector (ILD) is one of the
most popular traffic detectors in use. Classified
as a passive sensor, it works based on the
principle of mutual inductance. It detects
vehicle's presence by measuring the change
in inductance caused by the vehicle passing
over a wire loop buried under the road
The peripheral metal of the vehicle triggers an
electronics output relay or solid-state optically
isolated output, sending a pulse to the traffic
controller, signifying the presence of a vehicle
via vehicle detector card (VDC) which
triggers our advanced processing unit (APU)
to compute the next action based on our
The loop sensor cable is consisting of multi
strands copper cable insulated by PVC or
FEP (Fluorinated Ethylene Propylene).
Excellent flame-resistance and aging
resistance hence the long service life.
Great corrosion and oil resistance.
Strong acid and strong alkali resistance.
Good electrical insulation properties
and no moisture absorption.
Resistant to high voltage.
