Description

The DMU412B-500/LCT-M12 is an industrial-grade ultrasonic sensor designed for precise, non-contact distance measurement and object detection in challenging environments. With a measurement range of up to 500 mm, this sensor leverages ultrasonic echo-ranging technology to deliver reliable data regardless of target color, transparency, or material. The device is encased in a rugged, cylindrical metal housing rated IP67 for superior dust and water resistance, ensuring durability in harsh factory conditions. It features a 4-pin M12 quick-disconnect connector for easy installation and maintenance. With adjustable response times, temperature compensation, and programmable switching outputs, the DMU412B-500/LCT-M12 provides versatile and dependable performance for a wide range of automation tasks, from level control to positioning.

Features

  • Compact, Rugged Metal Housing: The nickel-plated brass housing provides excellent mechanical strength and corrosion resistance for use in harsh industrial environments.
  • IP67 Protection: Fully protected against dust ingress and temporary immersion in water, suitable for washdown areas and outdoor use.
  • Material-Independent Detection: Ultrasonic technology reliably detects objects regardless of their color, transparency, or surface texture (e.g., glass, liquids, dark materials).
  • Configurable Output & Teach-In Function: Offers flexible PNP/NPN switching or analog output. Simple push-button teach-in allows for easy setup of switching points without additional tools.
  • Temperature Compensation: Built-in compensation ensures stable and accurate measurements despite ambient temperature fluctuations.
  • Narrow Detection Beam: A small beam angle minimizes interference from background objects and enables precise detection of small targets.

Applications

  • Level Monitoring: Fill level detection of liquids, granules, or powders in tanks, silos, and bins.
  • Object Detection & Presence Checking: Detecting the presence/absence of products, boxes, or components on conveyors, pallets, or assembly lines.
  • Distance Control & Positioning: Precision positioning of machine parts, robotic grippers, or elevators.
  • Roll Diameter Measurement: Monitoring the diameter of material rolls in printing, packaging, and textile machinery.
  • Coil & Loop Control: Maintaining loop size in material handling systems for wires, cables, and textiles.
