Leuze Sensor DMU430B-6000/4TC-M12 Ultrasonic distance sensor

A long-range M30-threaded ultrasonic sensor with a 6000 mm (6-meter) sensing range and a standard M12 connector. The “4TC” designation typically indicates a switching output (often dual-channel or programmable) with an integrated Teach-in function for precise window setting.

Description

The DMU430B series is engineered for stability in large-scale environments. Using Time-of-Flight (ToF) technology, it is unaffected by the optical properties of the target, making it highly effective for measuring bulk solids, liquid surfaces, or large moving vehicles. The large transducer face allows it to cut through dust and humidity more effectively than smaller M12 or M18 models.

Features

  • Extended Reach: A 6-meter range makes it suitable for large silos, warehouse bays, and outdoor infrastructure.
  • Teach-in Function (T): Allows the user to easily set the switching points or the sensing window boundaries via a dedicated pin or button.
  • M30 Robust Housing: The large diameter provides the mechanical stability and surface area needed for long-distance acoustic projection.
  • Material Independent: Reliably detects “difficult” targets like wastewater, grain, wood, and metal plates regardless of color or transparency.
  • Temperature Compensation: Automatically adjusts for changes in the speed of sound caused by air temperature fluctuations to maintain accuracy over the full 6-meter span.
