The t coil requires a perpendicular verti cal in this case orientation to the loop wire or it will not pick up the loop signal.
Induction loop cable size.
An inductive loop system consists of these components.
Caltrans inductive loop detector type 2.
Vehicle loops and loop detectors are used to detect the presence of a vehicle to open a gate or as a safety device to prevent the gate from closing on a vehicle in its path.
A loop loop extension cable and a detector.
Loops are mostly installed in a quadratic or rectangular form.

When installing or repairing an inductive loop system the smallest detail can mean the difference.
Caltrans inductive loop detector type c.
Induction loops are used for transmission and reception of communication signals or for detection of metal objects in metal detectors or vehicle presence indicators.
These characteristics relate to the size shape and number of turns of wire and are detailed below.
An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire.
A 100m reel of white 1 5mm2 single core cable.
Loop wire can be at ceiling height or on the floor but should never be within the area of use.
Inductance loops are available as direct burial or cut in.
For exiting the property and especially safeties for closing inductive loops are the best.
