Leuze Sensor DMU318-400.W3/4VK-M12 Ultrasonic distance sensor

Description

The DMU318-400.W3/4VK-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 or require an awkward mounting bracket.

As a Time-of-Flight (ToF) sensor, it is immune to the optical “traps” that affect laser sensors, such as transparent glass, liquid surfaces, or high-gloss metal parts. The “4VK” configuration is particularly versatile for modern automation; it provides a high-resolution 0–10 V analog signal for real-time distance tracking, while the integrated IO-Link 1.1 protocol allows for digital data streaming and remote parameterization.

Features

90° Angled Head (W): Provides a critical solution for lateral installation in confined spaces where vertical clearance is non-existent.
Short-Range Precision: Optimized for a tight 40–400 mm window, providing high-resolution detection for small parts or narrow containers.
Hybrid 0–10 V & IO-Link Output: Offers the best of both worlds—simple analog integration for legacy systems and deep digital data diagnostics for Industry 4.0.
Onboard Teach Button (3): Features a physical button on the rear of the housing for rapid manual calibration of the sensing window without external tools.
Chemical-Resistant PBT Housing: The high-grade plastic (Polybutylene terephthalate) construction provides excellent resistance to industrial cleaning agents and reduced weight (approx. 70g).
Automatic Temperature Compensation: An internal sensor corrects for air density changes to ensure the measurement remains accurate even as factory temperatures fluctuate.

Applications

Small Bottle & Vial Detection: Detecting the presence of clear glass or plastic containers on high-speed liquid filling lines.
Robotic Gripper Integration: Mounting on end-of-arm tooling where the 90° head allows for a low-profile mechanical footprint.
Feeder Bowl Monitoring: Tracking the fill level of small parts in vibration feeders or hoppers with low overhead clearance.
Loop Control in Narrow Webs: Measuring the slack of thin ribbons, foils, or wires in processing machinery.
Electronic Component Positioning: Precise distance feedback for PCB boards or small trays during pick-and-place operations.
