Capacitive proximity sensor
ø 18 mm EMX Industries Inc.

The sensitivity adjustment must be done when the sensor is installed in a definite and steady position. The regulation must be done in a position half way between minimum and maximum, because, being air dielectric, a strong humidity variation could cause, if the regulation is very light, nuisance tripping.
The sensing distance ofthe sensor depends on the kind of material to detect and on its dimensions {see table about reduction factors).
The distance could change according to temperature variations. To increase the sensitivity twist the trimmer clockwise, to decrease do it anti c|ockwise.
