Selet has designed a new series of capacitive sensors with more compact dimensions than the traditional sensors on the market: 40mm, in total, of which 33 mm belonging to the threaded part for the flush version, and 50 mm, in total, for the non-flush version.
New constructive technology has allowed the creation of such products.
The sensitivity adjustment does not occur through a trimmer but using a teach-switch placed at the back of the sensor.
