DMU412B-500/LCT-M12 Ultrasonic distance sensor

The Leuze DMU412B-500/LCT-M12 (Part No. 50150586) is a high-precision ultrasonic distance sensor designed for non-contact measurement in demanding industrial environments. Unlike optical sensors, it uses sound waves to detect objects regardless of their color, transparency, or surface finish, making it highly effective for liquid level monitoring and detecting clear materials like glass.

Description

The Leuze DMU412B-500 is a cylindrical ultrasonic sensor that provides highly reliable non-contact distance detection. By using sound waves, this sensor can detect objects that are difficult for optical sensors to recognize, such as clear glass, liquid surfaces, or dark-colored materials. With a resolution of under 0.3 mm and internal temperature compensation, it ensures consistent data across varying environmental conditions. The integration of IO-Link allows for intelligent parameter configuration and real-time device diagnostics directly from the control system.

Specifications

  • Measurement Range: 15 mm to 500 mm.
  • Outputs: Dual output capability featuring 1x Analog (4–20 mA) and 1x Digital Switching (Push-pull, IO-Link).
  • Interface: Supports IO-Link (Version 1.1) for advanced configuration and diagnostics.
  • Resolution: Extremely fine, at < 0.3 mm.
  • Design: Compact M12 cylindrical metal housing (nickel-plated brass).
  • Beam Angle: Narrow opening angle of 3° to 11° to prevent interference from nearby machine parts.
  • Environmental Protection: Rated IP67, making it resistant to dust and water immersion.

Features

  • Teach-in Input: Allows for easy setting of the measurement range and switching points.
  • Synchronization: Supports Multiplex and Synchronous operation, allowing multiple sensors to be used in close proximity without signal interference.
  • Temperature Compensation: Features internal drift compensation (2%) to maintain accuracy despite ambient temperature changes.

Applications

  • Level Sensing: Monitoring the height of liquids or small parts in hoppers.
  • Web Tension Control: Measuring the diameter of rolls or the sag in a material web.
  • Stack Height Control: Ensuring precise positioning in packaging and palletizing lines.
