Loop Detector Module
Loop detectors in recent years have become a popular tool having innumerable applications in policing, right
from surveillance operations to traffic control. Automation of gates and doors has become a popular usage of the
The digital technology of the loop detector enables the equipment to sense a change in the inductance of the loop
as soon as it detects the metal object in its path. The inductive loop which detects the object is made of insulated
electrical wire and is arranged either as a square or rectangle shape.
The loop consists of several loops of wire and consideration should be giving to the loop sensitivity when
installing on different surfaces. Setting the correct sensitivity allows the loops to operate with maximum
detection. When detection occurs, the detector energises a relay for the output. This energising of the relay can be
configured, to three different modes, by selecting the output switch on the detector.
