Summary: | 1. Process for manufacturing an inductive sensor having a housing and a coil former which is adapted to be produced by injection moulding and in which a pin-form ferromagnetic iron core, a permanent magnet, and possibly a back-circuit plate, are arranged coaxially one behind the other, and the coil former is surrounded in the region of the iron core by an induction coil the beginning and end of which coil are connectable to contact lugs of a connection element, characterised in that, for the injection moulding of the coil former (3), the iron core (5) and the permanent magnet (6) and possibly the back-circuit plate (7) are so placed in a coil former mould that that end of the iron core (5) which is opposite from the permanent magnet (6) is held in an axial recess of the coil former mould, and the permanent magnet and/or the back-circuit plate (7) and/or the iron core (5) are held by radially abutting radial cores. |
