Leuze Sensor DMU318-1600.3/2VK-M12 Ultrasonic distance sensor

Description

The DMU318-1600.3/2VK-M12 utilizes Time-of-Flight (ToF) technology, emitting a high-frequency acoustic pulse and measuring the precise micro-interval required for the echo to bounce off a target and return. Because it relies on sound rather than light, it is a superior choice for detecting “difficult” targets such as clear glass, liquid levels, dark plastics, or metallic foils.

The “2VK” configuration is designed 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 “Smart Sensor” capabilities. This includes the streaming of real-time digital distance values and remote teaching of switching windows via a PLC, which is ideal for machines with frequent product changeovers.

Features

Hybrid 0–10 V & IO-Link Output: Offers the simplicity of a legacy analog voltage signal for immediate PLC integration while supporting modern digital data exchange.
Onboard Teach Button (3): Enables rapid manual calibration of the sensing window and switching points directly on the sensor body without needing external software.
Mid-Long Reach: A 1.6-meter range makes it suitable for larger tanks, wide conveyors, and pallet detection.
Robust Plastic Housing: Constructed from chemical-resistant PBT (Polybutylene terephthalate), offering significant weight savings and resistance to industrial cleaning agents.
Integrated Temperature Compensation: An internal sensor automatically adjusts the distance calculation to account for changes in the speed of sound caused by air temperature fluctuations, maintaining an accuracy of $pm 1%$ .
