Leuze : New Ultrasonic sensors
If you ’ re looking to reduce the number of different sensors used in your systems , the 420B and 412B series from Leuze are the right choice : The new ultrasonic sensors are available with adjustable sound cone and as switching ( HTU ) or measuring ( DMU ) sensors – this allows extremely flexible application . The sound cone can be set via an IO-Link interface to the three ranges “ narrow ”, “ medium ” or “ wide ” and thus adapted to the respective application . As a result , the ultrasonic sensors operate with maximum precision : They are able to detect reliably in situations where optical sensors are pushed to their limits . They also detect glossy , reflective , very dark or transparent surfaces as well as liquids without problem . The 420B series includes ultrasonic sensors in compact cubic plastic housings . It replaces the 420 series . With the new devices , users benefit from smaller dead zones with the same or a higher sensor operating range . The 412B series complements the range of cylindrical sensors in M12 housing with devices featuring IO-Link and analog output .
Maximum flexibility in the red housing
Thanks to their adjustable sound cone , IO-Link interface and two switching outputs , the HTU420B ultrasonic sensors in the red housing are suitable for challenging detection tasks . For example , two fill levels
The ultrasonic sensors of the 420B series have an adjustable sound cone . A narrow , medium or wide sound cone can be selected depending on the application . This allows , for example , fill levels to be monitored through differently sized container openings
With the new devices , users benefit from smaller dead zones with the same or a higher sensor operating range .
can be detected or two positions can be monitored simultaneously . The adjustable sound cone turns the sensors into flexible all-rounders . A narrow sound cone , for example , is suitable for detecting a fill level through small container openings . In its wide setting , the sound cone in turn captures larger areas – ideal in the case of bulk material or diffusely reflective objects with complex surface or structure . Practical : An interruption filter detects brief
changes in measurement within a certain interval caused by interfering objects ( e . g . an agitator ). The sensor suppresses these interfering signals via the IO-Link interface , thereby ensuring a seamless production process .
For the precise measurement of distances
Moreover , to measure distances , system operators can make use of the DMU420B and DMU412B ultrasonic distance sensors . The devices have an analog output ( either current or voltage ), an IO-Link interface as well as an adjustable sound cone .
Economical solution in the black housing
The Sensor People from Leuze also offer the HTU420B ultrasonic sensors in a standard design with black plastic housing . As an economical solution with one switching output ( push-pull ), they are suitable for simple detection tasks . Both variants are available in the operating ranges from 10 to 250 millimeters , 15 to 500 millimeters as well as 20 to 1000 millimeters . The HTU412B series has an operating range of 15 to 500 millimeters .
Fast setup
Thanks to an adjustable sound cone and small dead zone , the new Leuze ultrasonic sensors of the 420B and 412B series can be used for many different applications .
The cubic sensors measuring 20.5 x 41.0 x 15.0 millimeters are extremely compact . The cylindrical sensors of the HTU412B series too are just 50 millimeters long . They are therefore also particularly suitable for applications in constrained spaces . All types can be parameterized quickly : Easy setup and operation is possible using the teach button , via the teach input or via IO-Link .
