Overview

M12 capacitive proximity sensor features an unshielded installation design, a detection distance of 5mm, an IP67 protection level, strong anti-interference capabilities, a compact size, and a long lifespan. 8 different outputs are available. SUCH capacitive proximity switch can detect both non-metallic materials (such as plastics and liquids) and metallic materials, making it suitable for applications including liquid level monitoring and powder height measurement.

Feature

The capacitive proximity sensor provides a 5mm sensing distance and uses an intelligent sensing chip for fast response, strong anti-interference performance, and accurate NO/NC metal detection.
It features a durable nickel-plated brass M12 threaded housing with good anti-interference capability and long service life.
SUCH proximity switch is equipped with an LED indicator that turns on in the normally-open mode and stays off in the normally-closed mode when detecting metal objects.

FAQ

Q1: Why does the indicator light show a signal but there is no signal output? ❯

This may be caused by wiring errors between the sensor and the device, incorrect operating voltage, or equipment short circuits. These issues can burn the internal circuitry of the sensor, leading to damage and failure.

Q2: Why does the indicator light stay on without signal changes, or keep blinking? ❯

This can result from poor connections or unstable short circuits in the device circuit, which cause non-destructive internal damage to the sensor and lead to abnormal indicator behavior.

Q3: Why does a wiring error or short circuit make the sensor completely unavailable? ❯

Some sensors have no built-in protection functions. Therefore, wiring mistakes or short circuits can directly damage the sensor and cause it to stop working.
