Leuze Sensor DMU330-6000.3/4CK-M12 Ultrasonic distance sensor

A heavy-duty M30-threaded ultrasonic sensor with a 6000 mm (6-meter) sensing range and a standard M12 connector. The “4CK” designation indicates a switching (digital) output—typically a Push-Pull configuration—with an integrated IO-Link interface for advanced diagnostics and configuration.

Description

The DMU330 series utilizes Time-of-Flight (ToF) technology, emitting high-frequency sound pulses to detect targets regardless of their color, transparency, or surface texture. This model is particularly effective for monitoring bulk solids, liquid levels in large tanks, or the presence of large vehicles. The inclusion of IO-Link allows for remote parameter setting and real-time monitoring of the sensor’s health.

Features

  • Extended 6-Meter Reach: Ideal for large-scale applications such as silos, warehouse bays, and outdoor infrastructure.
  • IO-Link Integrated: Enables “Smart Sensor” capabilities, including remote teaching, distance value transmission via the process data, and diagnostic alerts.
  • Push-Pull Switching Output: A universal output that can act as PNP or NPN, making it compatible with almost any PLC architecture.
  • Material Independent: Reliably detects “difficult” targets like wastewater, grain, wood, and metal plates without being affected by optical interference.
  • 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.
