The USi-safety evaluation unit is designed to meet Category 3 Performance Level d (PL d) as per EN ISO 13849, providing safety functionality for ultrasonic transducers without redundancy. This unit supports multiple device installations without risk of mutual interference, ensuring reliable performance in safety-critical applications.
The USi-safety evaluation unit is a sophisticated component within the Pepperl+Fuchs ultrasonic sensor family, designed specifically for applications that require enhanced safety features. It excels in environments where precise distance measurement and reliable object detection are paramount. The unit operates with multiple ultrasonic transducers, offering a robust solution for various automated processes while maintaining compliance with strict safety standards.
One of the key features of this evaluation unit is its ability to provide safety outputs through OSSD (Output Signal Switching Device), which ensures that the safety functions are upheld without redundancy. The adjustable sound cone and integrated temperature compensation enhance its operational flexibility, allowing users to tailor the unit’s performance to specific application needs. Furthermore, parameterization, commissioning, and reporting are streamlined via dedicated software, simplifying setup and maintenance tasks.
