Ultrasonic sensors offer versatile applications for detecting transparent, dark, glossy, reflective or porous surfaces as well as detecting objects or liquids, even under adverse conditions such as contamination, dust, mist or ambient light. The measurement is carried out by transmitting and receiving ultrasonic waves, the results of which are either output as an analog or switching output or transmitted via IO-Link.
The sensors can be used in various operating modes, such as synchronous, multiplex, reflex or throughbeam mode. In synchronous mode, up to 40 sensors can be used together depending on the sensor type and thus cover a larger area. Multiplex mode prevents mutual interference between adjacent or opposing sensors. Depending on the application, ultrasonic sensors are available in different housing formats, from the space-saving cylindrical or cubic format to the fork format.
