A housing is made of bakelite board and a 10mm copper rod is fitted tightly into a hole drilled in the centre of the housing . The two ends of the rod have thread for M10 brass nuts. A slot is provided in the centre Bakelite piece, for sliding in the Hall Effect sensor. See next picture:

housing

The sensor, together with its resistor and de-coupling capacitor is soldered onto the vero-board and fasened to the bakelite housing with non ferrous self tapper screws. See picture below:
