Inductive Proximity Sensor LJ12A3-4-Z/BX Metal Detecting NPN NO 3 Wire DC 6-36V

Inductive Proximity Sensor LJ12A3-4-Z/BX Metal Detecting NPN NO 3 Wire DC 6-36V

PLEASE CHECK your wiring is correct, incorrect wiring won’t trigger your device. See wiring layout below or in photos.

This is a module specifically designed to detect metal. The module

operates by inducing currents in metal objects and responding when it

occurs. These are commonly seen in 3d printers for auto levelling.

NOTE: there is no wiring sticker on the unit.
