Leuze Sensor DMU230-3000/LA-M12 Ultrasonic distance sensor

Description

The DMU230 series utilizes Time-of-Flight (ToF) technology to measure the distance to a target regardless of its color, transparency, or surface texture. The LA designation signifies a Linear Analog (Current) output. A 4–20 mA signal is the industrial standard for reliability because it is highly resistant to electromagnetic interference (EMI) and can travel hundreds of feet to a PLC without the voltage drops that plague 0–10V systems.

Features

Extended Reach: A 3-meter sensing range allows the sensor to be mounted safely away from moving machinery or hazardous zones.
4–20 mA Analog Output: Provides a stable, noise-resistant signal that scales linearly with the measured distance.
M30 Large Diameter Housing: The larger transducer face produces a stronger acoustic pulse, which better penetrates dusty, humid, or turbulent air than smaller M12 or M18 models.
Internal Temperature Compensation: Automatically corrects for variations in the speed of sound caused by air temperature changes, ensuring consistent accuracy over the full 3-meter span.
IP67 Protection: Fully sealed against dust and water ingress, suitable for outdoor use or industrial washdown areas.
