Flush or non-flush for sensors
What is meant here by flush or non-flush?
Flush / Non-flush (aka f / nf) are important details that appear in data sheets on inductive sensors. As the name indicates, flush-mountable sensors can be fully integrated into the surrounding metal up to the uppermost sensor face. Non-flush sensors, on the other hand, require some free space around the sensing face. Generally, non-flush sensors protrude a little from the surface. Manufacturers often clearly identify non-flush sensors with the aid of coloured caps. The thread ends below this cap, so the user can readily see that the sensor should not be completely recessed into the metal.
