Abstract

A method for producing capacitive sensors which is used in particular for the parallel production of capacitive sensors with exactly defined stray capacitance. For this purpose, troughs (15, 16, 17) are cut along or parallel to the splitting lines (6), so that adjustment errors in the position of the cut, during separation of the sensors, and variations in the cut width have no effect on the stray capacitance.
