Leuze Sensor DMU318-400.W3/2CK-M12 Ultrasonic distance sensor

Description

The DMU318-400.W3/2CK-M12 is the “short-range specialist” of the right-angle family. The “W” designation signifies that the transducer exit is directed at a 90° angle from the longitudinal axis of the PBT housing. This unique geometry allows the sensor to be “tucked” into narrow machine frames or low-profile conveyor side-walls where a straight sensor would physically collide with the target.

As a Time-of-Flight (ToF) sensor, it is immune to the optical properties of the target, reliably detecting clear glass, liquid levels, or highly reflective metal parts. The “2CK” configuration offers a high-speed Push-Pull switching output (compatible with PNP or NPN) and the IO-Link 1.1 protocol, which allows for digital distance value streaming and remote teaching of the switching window.

Features

90° Angled Head (W): Provides a solution for lateral installation in confined spaces where vertical clearance is non-existent.
Short-Range Precision: Optimized for the 40–400 mm window, providing high-resolution detection for small parts or narrow tanks.
IO-Link 1.1 Integrated: Enables bidirectional communication for remote parameter setting, health monitoring, and real-time digital distance data.
Push-Pull Switching Output: A universal digital output that eliminates the need to choose between PNP or NPN wiring, simplifying inventory.
PBT Plastic Housing: Constructed from chemical-resistant Polybutylene terephthalate, making it lightweight (approx. 70g) and suitable for harsh industrial cleaning environments.
Temperature Compensation: Automatically adjusts internal logic for changes in air temperature to maintain accurate switching points.
