The M8 NPN Normally Closed Inductive Proximity Sensor is used for non-contact metal detection, making it ideal for limit switch and homing functionality in CNC machines, 3D printers, and automation systems. This sensor activates when it is within 2mm of a metal surface, providing accurate, repeatable switching without mechanical wear.

The compact M8 size is perfect for installations with limited space, while the 3-wire NPN NC output ensures easy integration with most CNC controllers and breakout boards.
