ifm electronic’s KT touch sensor can
be used in applications that require a
pushbutton selector such as machine
start/stop, door openers and even on
a jacuzzi to turn the bubbles on/off.

Capacitive sensing technology
enables it to detect touch through a
variety of non-metallic materials
including plastics and glass, allowing
more than simple surface mount.

The one-piece
housing has no moving
parts. Users simply
touch the exterior
panel to produce a onepulse
output from the sensor which
features self-adjusting dynamic
switching that ignores build-up
including dirt, water and ice. The
housing diameter is 100mm overall,
but has a depth of just 11mm.
