Leuze Sensor DMU420B-250.3/LV-M8 Ultrasonic distance sensor

A miniature M12-threaded ultrasonic sensor with a 250 mm sensing range and a standard M8 connector. It delivers a continuous 0–10V analog output, allowing for real-time distance tracking and precise positioning.

Description

The A1M2 utilizes ultrasonic Time-of-Flight (ToF) technology, which makes it immune to the target’s color, transparency, or surface gloss. The LV designation signifies a Linear Voltage output. As the target moves within the 200mm active window, the sensor scales the distance into a proportional 0–1The A1M2 utilizes ultrasonic Time-of-Flight (ToF) technology, which makes it immune to the target’s color, transparency, or surface gloss.

Features

  • Analog Precision: Provides a 0–10 V DC output signal that scales linearly with the target’s distance.
  • Material Independent: Reliably detects clear glass, liquids, dark plastics, and multi-colored surfaces that often “blind” optical sensors.
  • Ultra-Compact M12 Housing: The small diameter allows for installation in very tight mechanical assemblies or dense sensor arrays.
  • High Resolution: Capable of detecting minute changes in distance, typically down to 0.05 mm or better depending on the controller’s resolution.
  • IP67 Protection: Fully sealed against dust and water ingress, suitable for high-speed industrial environments.

Applications

  • Precision Tension Control: Monitoring the “sag” of thin films or foils to adjust motor speed in winding machines.
  • Small Fluid Level Measurement: Providing a constant signal for the fill level of vials, small containers, or laboratory beakers.
  • Thickness Measurement: Detecting the thickness of boards, plates, or components by measuring the distance to the top surface.
  • Micro-Positioning: Providing feedback for the height of precision lift tables or small pneumatic actuator extensions.
  • Quality Inspection: Checking for the presence and correct height of small components on high-speed assembly lines.
