Proximity Inductive Sensor Range 4mm 6-36V
The Inductive Sensor Probe LJ12A3-4-Z/BX is capable of detecting metal without contact, and is often used in 3D printers to read or adjust the level of the Print Bed, including the RAMPS 1.4-based machines. This sensor helps identify any warping or sagging of a print bed and provides the necessary data for the firmware to readjust the Z endstop to accommodate for these subtle differences in height.
The benefits that this sensor provides includes better first-layer adhesion on large or simultaneous prints, greater accuracy for the firmware to print ultra-thin layers, as well as less hassle as you don’t need to manually readjust your Z endstop as the bed subtly warps over time. Just remember, however, that because this is an induction sensor, it will only work with metal print beds. The installation may also require some firmware modifications, which can be found on the RepRap Wiki, although this is relatively simple for any veteran Maker or 3D printer enthusiast.
