Clearance from metal objects/surfaces
Metal objects or surfaces parallel to the XT-EF sensor
or to the side can cause interference of the electrical
field which results into unstable behaviour. Please
take the clearances indicated in the table below into
account.
Clearance between XT-EF sensors side-by-side
When using multiple XT-EF sensors side-by-side the
electrical fields of the sensors will interfere with each
other when placing the sensors too close next to each
other. Therefore please make sure that the minimum
spacing indicated in the table below are taken into
account.
Double glazing
The XT-EF sensors do
not
work behind most types of double glazing used to insulate indoor environments from outdoor
environments (e.g. double glazing used in windows or doors at store fronts). The reason for this is that most modern
types of double glass have a very thin invisible metal foil inside to reflect heat. The metal foil blocks the electrical field
of the sensor, causing the sensor not to detect any AirButton or AirGestures. Next to that, some types of gas applied to
insulate the two glass panels may have a negative effect on the detection range.
Please note that the XT-EF sensor does work behind almost all other common types of glass, whether it is with 1 glass
panel or multiple.

Transceiving side
The XT-EF sensor electrode has a transceiving side
and non-transceiving side. This is indicated on the sen
-
sor at the bottom left. Make sure the sensor is placed in
such a way that the transceiving side is facing the user.
When using a top panel, the transceiving side should
be attached to the panel.
