| 摘要 |
The invention relates to an electronic switching device operating contactlessly, particularly comprising an ultrasonic sensor. The switching device consists of a basic device (1) accommodating the electronics and the mounting means (5) and a pick up head (7) which can be connected to this device in different positions via a connecting line. A tubular holding part (8), which is encircled by a pipe clamp (10), is connected to the basic device (1). Between the clamp ends (19 and 20), a holding projection (22) of the receiving part (11) is carried rotatably via a clamping screw and held after the latter has been tightened. The hysteresis of the clamp ends (19 and 20) holds both the holding projection (22) and the pipe clamp (10) on the holding part (8). <IMAGE> |
