Leuze Sensor DMU330-3500.3/2VK-M12 Ultrasonic distance sensor

Description

The DMU330 series utilizes Time-of-Flight (ToF) technology, emitting high-frequency ultrasonic pulses and measuring the precise micro-interval it takes for the echo to return from a target. Unlike optical sensors, the DMU330-3500.3/2VK is entirely unaffected by the target’s color, transparency, or surface gloss—making it an industry favorite for sensing clear liquids, dark plastics, and highly reflective metals. The “2VK” configuration is particularly powerful as it offers the simplicity of a legacy 0–10 V analog signal for immediate PLC integration while simultaneously supporting IO-Link 1.1 for remote parameterization, health monitoring, and digital distance value transmission.

Features

Hybrid Output Interface: Features both a 0–10 V DC analog voltage output for traditional control and an IO-Link interface for modern Industry 4.0 data exchange.
Extended 3.5-Meter Range: The powerful transducer allows for stable measurement over long distances, keeping the sensor safe from moving machinery or corrosive chemical vapors.
M30 Robust Housing: The large diameter housing provides the mechanical stability and surface area needed for high-power acoustic projection and reception.
Integrated Temperature Compensation: An internal sensor automatically adjusts the distance calculation to account for changes in the speed of sound due to air temperature fluctuations, maintaining accuracy within $1%$ .
IP67 Environmental Protection: Fully sealed against dust and water ingress, suitable for high-humidity environments, washdown areas, and outdoor silos.
