DMU420B-1000.3/LC-M8 Ultrasonic distance sensor

A compact M8-connected cubic ultrasonic sensor with a 20–1,000 mm range. It features an analog current output (4–20 mA) and IO-Link integration, making it ideal for high-precision level and distance monitoring in tight spaces

Description

The DMU420B-1000.3/LC-M8 is a versatile measuring tool that utilizes ultrasonic waves to determine distance, ensuring reliability in dusty, humid, or vaporous environments. Its red plastic housing is extremely compact (20.5 x 41 x 15 mm), allowing for easy integration into constrained machinery.

This model features a non-linear 4–20 mA current output and a push-pull digital switching output. With IO-Link V1.1 support, users can access advanced diagnostics and adjust the sound cone width to filter out interfering objects like agitators or machine frames. The integrated teach button allows for quick on-site range adjustments without external software.
