Leuze Sensor DMU420B-1000.3/LC-M8 Ultrasonic distance sensor

Description

The “DMU” series is known for its robust performance in dusty or humid environments. By emitting high-frequency sound waves and measuring the Time-of-Flight (ToF), it calculates the distance to an object regardless of its color or surface texture. The LC (Low Cost/Compact) designation indicates a streamlined design optimized for high-volume OEM integration without sacrificing sensing accuracy.

Features

Material Independent: Detects liquids, clear glass, plastic films, and multi-colored objects with equal precision.
Push-Pull Output: A versatile “universal” output that can operate as either PNP or NPN, reducing the need to stock multiple sensor types.
Narrow Beam Angle: Designed to minimize “stray” reflections from side walls or machine frames, allowing for use in tighter spaces.
M8 Plug Connection: Uses a standard 3-pin M8 circular connector for fast, vibration-proof installation.
Status LEDs: Typically includes high-visibility LEDs to indicate power (Green) and switching status (Yellow).
