Leuze HTU420B and DMU412B ultrasonic sensors

Click2Contact

The Leuze HTU420B and DMU412B ultrasonic sensors in M12 housings are designed to be used for many different applications — for switching (HTU) and measuring (DMU) applications — and offer an adjustable sound cone.

The sound cone can be set via an IO-Link interface to the three ranges — narrow, medium or wide — to adapt to the respective application. They also detect glossy, reflective, very dark or transparent surfaces and liquids.

The HTU420B ultrasonic sensors (red housing) are suitable for challenging detection tasks. For example, two fill levels can be detected or two positions can be monitored simultaneously. The adjustable sound cone turns make the sensors more flexible: a narrow sound cone, for example, is suitable for detecting a fill level through small container openings, while in the wide setting, the sound cone in turn captures larger areas — useful in the case of bulk material or diffusely reflective objects with complex surface or structure. An interruption filter detects brief changes in measurement within a certain interval caused by interfering objects (such as an agitator) suppressing these interfering signals via the IO-Link interface.

The DMU420B and DMU412B ultrasonic distance sensors have an analog output (either current or voltage) and an IO-Link interface.
