摘要:
The invention relates to a method of manufacturing an inductive proximity switch, in which an enclosure is formed from a single piece of a non-ferromagnetic metal and electronic components are inserted into the enclosure, and to a corresponding proximity switch. The electronic components comprise a coil configured to be supplied with transmitting current pulses and a processing circuit configured to generate an output signal based on received voltages induced in the coil after the duration of the transmitting current pulses.In order to fabricate a proximity switch with an improved robustness by maintaining its proper functionality, the invention suggests that forming of the enclosure comprises the step of deep drawing a sheet of the non-ferromagnetic metal to a tubular element with a front wall covering its front end and a side wall delimiting an inner space for receiving the electronic components.
