Small Housing – Smart Core: U1KT Miniature Ultrasonic Sensors

The U1KT ultrasonic sensors are available in miniature design and can be used in both reflex and through beam mode. Their small size and light weight make them ideal for particularly confined spaces. These ultrasonic distance sensors are perfect for installation in narrow close-range situations due to their small format and minimal blind spot. They are ideally suited for detecting transparent, glossy and dark objects as well as reflective surfaces and a wide range of materials.

Application Video: Protective Foil Processing with Ultrasonic Distance Sensors

Precise detection of transparent surfaces is one of the most demanding tasks in the automation industry. To meet this challenge, Foilpuller GmbH, an expert in the processing of protective foils, relies on the powerful ultrasonic sensor U1KT001. This sensor enables reliable detection of objects regardless of their material, thickness or color and can be optimally integrated into small systems thanks to its extremely compact dimensions of only 32 × 16 × 12 mm.

Function of the Sound Runtime Measurement

Ultrasonic distance sensors use the principle of sound runtime measurement. The active surface on the front part of the sensor emits ultrasonic waves that are reflected by the object and received by the sensor. The ultrasonic sensors calculates the distance to the target object by measuring the time between the emission and receipt of the sonic pulse.

Typical applications: 
  • Distance measurement
  • Fill level monitoring

Narrowing of the Sonic Cone by Soundpipe

The soundpipe narrows the sonic cone of the U1KT ultrasonic sensors. The use of the soundpipe prevents objects in the edge area of the sonic cone from being detected. Precise sound guidance enables you to precisely measure and detect small openings and boreholes as well as reliably detect fill levels in small containers.
