Abstract
A proximity sensor H with a feeler element 16, 17 which is provided in a holder 22 and is directed towards the motion range of a magnet 28 which is movable in relation to Hall element 16 and can be caused to respond to said magnet 28 has at least one metal trimming body T, 27 in the vicinity of the sensor element such that said trimming body can be adjusted in its distance from said sensor element. The response sensitivity of said proximity sensor H can be varied by a distance adjustment of said trimming body. The proximity sensor H equipped with said trimming body T. 27 suitably is provide in a yarn feeder as a yarn sensor G or a speed- or counting sensor D and is adjustable with respect to its response sensitivity by means of said trimming body.
