Leuze Sensor DMU318-1600.W3/4CK-M12 Ultrasonic distance sensor

A compact M18-threaded ultrasonic sensor with a 1600 mm (1.6-meter) sensing range and a 90° angled sensing head (W). It features a hybrid output system providing both a 4–20 mA analog current signal and a PNP switching output, all configurable via a built-in Teach-in button (3).

Description

The DMU318-1600.W3/4CK-M12 is engineered for applications where a standard “straight-ahead” sensor cannot fit due to mechanical interference. The “W” designation signifies the right-angle optics, where the sound exit is directed 90° away from the longitudinal axis of the M18 body.

Using Time-of-Flight (ToF) technology, the sensor is immune to target color, transparency, or gloss. It is a preferred solution for level monitoring in small tanks with low overhead clearance or for detecting objects on high-speed conveyor lines where the sensor must be tucked away. The “4CK” configuration provides a stable 4–20 mA current loop for continuous distance measurement and a PNP digital output for limit detection, both of which can be calibrated using the onboard teach button for high-precision windows.

Features

  • 90° Angled Design (W): Allows for lateral installation in tight machine spaces where vertical or direct-facing clearance is limited.
  • Analog & Digital Hybrid: Combines a 4–20 mA analog current output for distance tracking with a PNP switching output for threshold alerts.
  • Onboard Teach Button (3): Enables quick, manual calibration of the sensing range and output logic without needing external software.
  • Stable Plastic Housing: Constructed from robust PBT (Polybutylene terephthalate), offering chemical resistance and weight savings (approx. 70g) over metal variants.
  • Temperature Compensation: Automatically corrects for variations in the speed of sound caused by ambient temperature changes, maintaining accuracy over the 1.6-meter span.
