The compact ultrasonic sensor module detects objects using ultrasonic waves, which are transmitted and received with only one piezoelectric disc. Here, an integrated driver and signal processor is used for signal generation and processing. The very compact design transforms the ultrasonic sensor module into a highly robust and versatile component with excellent EMC characteristics, which thanks to the solid aluminum housing is also protected against dust and splash water. As such, it is ideally suitable for numerous industrial applications and applications in harsh environments.
