Can you link what you bought please?
Sorry - it was sufficiently long ago that that seller doesn't seem to have them any more. They were "LJ12A3-4-Z/AX NPN NC 4mm Inductive Proximity Sensor Switch DC 3-wire 200mA", which are available from quite a few other suppliers. I paid £23 for a box of 10 but again, prices vary and that was a couple of years ago.
