SN04-N 3D Printer Inductive Proximity Switch Sensor NPN DC 5-36V 4mm Range


This Inductive Proximity Switch is widely used in automatic control industry for detecting, controlling, and noncontact switching. When proximity switch is close to some target object, it will send out control signal. This makes it perfect for heat bed proximity detection by the printing head for 3D Printers.

The SN04-N 3D Printer Inductive Proximity Switch is for those who use 3D printing a lot, manually leveling a 3D printer can be time consuming and a bit mysterious. Getting it “just right” requires a good eye and constant attention while printing the first layer. Thankfully, there’s Auto-leveling. The SN04-N 3D Printer Inductive Proximity Switch will save your 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. Using this switch for 3D Printers will produce less issues related to un-level print beds like parts coming up on one corner and nozzles jamming because the print started too close.
