Two New Ultrasonic Sensors for Switching and Measuring

Fully metal-enclosed ultrasonic sensors with degree of protection IP 67, longer operating ranges and thus broader areas of application expand the Leuze electronic line of ultrasonic sensors.

The HTU 418B and DMU 418B switching and measuring devices, respectively, have an operating range of up to 1300 mm; the DMU 430B measuring devices have an operating range of up to 3000 mm. The series are available in cylindrical M18 as well as M30 metal housings – with much shorter design compared to the predecessor models. They can thus be easily installed in application locations with limited space using the lock nuts on the external threads. Both series were equipped with an improved teach function: two push buttons for defining two independent switching points simplify setup and increase flexibility when using the sensors.

Device types with an IO-Link interface ensure the intelligent, simple and user-friendly connection and activation of the sensors. Temperature compensation prevents measurement errors that could be caused by various environmental conditions. Four operating modes, e.g., for changing from synchronous to multiplex operation, offer high flexibility during use. The ultrasonic sensors convince through a switching behavior that is largely independent of the surface of the sound-reflecting materials. They are available with various sound lobes, i.e., with different opening angles. The narrow sound lobes in particular permit the detection of the smallest of objects or the detection through the smallest of apertures at short response times.
