Inductive Vehicle Loop Detector for Car Parking Management System
Quick Detail:
The PD-123 is a single channel inductive loop detector designed for
parking and access control applications.
The detector is connected to an inductive loop mounted in the road
surface. When vehicles pass over the loop the detector switches on
an output.
The use of microprocessor and surface mount technology enables a
large number of functions to be incorporated into a small package.
The PD-123 is compatible with most single channel detectors on the
market and is easy to set-up and install.

Application
Loop detectors are used wherever vehicles have to be detected. Like
monitoring and safe guarding access ways to counting vehicles. The
output signal can be used for controlling door and gate drive
mechanisms, operating barriers, controlling traffic light systems
in car parks or activating card dispensers in car parks.
The PD-123 is a single channel inductive loop detectors. The
principle is based on a change in the inductance within the loop
which is caused by the metallic components of passing vehicles. The
changes are picked up and evaluated by a microprocessor. Ease of
use thanks to automatic calibration when the operating voltage is
applied.
