This inductive proximity switch is designed to improve the accuracy and efficiency of the auto leveling process for 3D printers. Its exterior, made from ABS, is highly water-resistant, while keeping its good inductive capability.

For those who 3D print a lot or 3D printing beginners, it makes leveling the build platform a no-brainer. This feature will enable your printer to take several bed leveling readings and calculate a level plane so your prints are always level. While printing each layer, you z-axis will be in constant motion to compensate for an un-level bed.


Save time messing with springs and screws on your print bed. Run the Auto-level procedure before every print or just one time for each start-up of the printer.

Less issues related to un-level print beds like parts coming up on one corner and nozzles jamming because the print started too close.

Note: To set up your printer for auto-leveling, you need to update your firmware and make a mount for your Inductive Proximity Switch.
