Ultrasonic Distance Sensors Provide Easy Integration

Wenglor’s new U1RT series ultrasonic distance sensors combine with tried-and-tested ultrasonic technology setting new standards in range and integration options. With IO-Link 1.1 and NFC interface the sensor offers flexible setting options and data storag-

Combining two successful products and installing these technologies in an established sensor housing design results in this new generation of U1RT ultrasonic reflex sensors. In through-beam mode, the sensor operates reliably at up to 2,000 mm, in reflex operation up to 1,200 mm is possible.

In addition to the application range at temperatures between –30 and +60 °C, it’s also possible to use the sensors in synchronous mode. Two independent switching outputs enable the measurement of minimum and maximum levels. All-round visible LED indicators and high IP67/IP68 degree of protection are also included.

Flexibility and Smart Communication

The high application flexibility is made possible not only by the low installation depth, but also by the availability of PNP and NPN variants. “But the new U1RT series sensors can do much more”, explains wenglor product manager Maria Boos. “The integrated IO-Link 1.1 interface with COM3 standard enables fast and secure communication with controllers. Thanks to the Smart Sensor Profile, the product can be easily integrated into IO-Link in a standardized way and regularly sends status messages.”

The integrated NFC interface allows for the sensors to be configured without power and wirelessly via the wenglorApp – which is ideal for applications with high quantities and saves a lot of time. Speaking of saving time: The sensor can be adjusted directly via the teach-in key with just a few buttons. Product manager Maria Boos is certain: “The long ranges combined with the tried-and-tested R format and smart integration options make the U1RT series a real all-rounder for the industry.”

Versatile Portfolio for Every Application

In addition to extremely compact formats such as the U1KT housing (32 x 16 x 12 mm) and the R format (56.5 x 26 x 24 mm), the ultrasonic sensors product also includes metric designs in M18 and M30 format (UMD and UMF) made of stainless steel as well as the cuboidal UMS sensors (81 x 55 x 30/47 mm) for large working distances of up to 6,000 mm and the special U1H format as a fork sensor.

Ultrasonic Technology

Ultrasonic sensors are ideal for contactless detection of transparent, glossy and dark objects, reflective surfaces and materials of all kinds – whether solid or liquid, rough or smooth, porous or translucent. Environmental conditions such as dust, steam, dirt or the influence of ambient light do not disturb them. “By emitting and receiving pulsed ultrasonic waves, the sensors, like bats, use the time it takes for the sound to be reflected by the object to determine its distance”, Boos continues. “Level measurement, stack height checks, checking slack in roller material or even checking for the presence of e.g. cans or PET bottles in automatic return machines are just a few applications that can be solved with this technology.”
