## Description

3-wire PNP inductive sensor for detecting metal proximity, useful in automation, CNC and industrial projects, detects up to 5 mm depending on the surface and can also work through thin non-metallic materials, 10-30VDC power supply, NO contact with PNP output, red status LED and IP67 protection for use in harsh environments.
Inductive sensor, PNP, SN04, with 3 wires, which detects the proximity of a metal surface through the principle of induction.
It can detect up to a distance of 5mm, depending on the type of surface and its shape.
It can also be used for detection through thin non-metallic surfaces.
It has a red LED that lights up when a metal object is near.
The sensor is of the Normal Open type: the supply voltage will be present on the signal wire if there is no metallic surface in contact; the voltage will drop close to 0 in the absence of contact with the metal surface.
