Detection principles
CAPT detects objects near the safety edge of the gate by detecting variations between conductive part of the gate and
conductive parts of the safety edge.
For that reason CAPT has a cable to connect GND to the metal part of the gate.
It is very important for the proper working of the NO TOUCH detection that the ground
reference is properly connected.
The measurement is going to
depend on:
•
Size of the conductive
part of the object.
•
Distance from the
object to the edge of
the gate.
Maximum safety edge length=
2.5m.
