Pepperl+Fuchs Debuts Ultrasonic Sensor for Safety ApplicationsOctober 19, 2021
Pepperl+Fuchs, Twinsburg, OH, has expanded its factory-automation portfolio with the new USi-safety ultrasonic sensor. Suitable for use in harsh environments and even for outdoor applications, the small sensor requires a minimal amount of installation space and boasts safety certification to EN ISO 13849 category 3 PL d.
The USi-safety is a two-channel ultrasonic sensor featuring two transducers connected to a control interface. On each of the two independent channels, objects can be detected via an elliptical sound beam within ranges of up to 2500 mm. Two safe OSSD outputs are provided for signal output.
Due to the special wide and shallow shape of the detection field, the system can be used just above the floor or close to a wall. It has been perfected, say company officials, for monitoring in three-dimensional space to offer optimal protection of machines, vehicles and workers--while conventional ultrasonic sensors emit acoustic signals in the form of a radially symmetrical sound beam, the USi-safety does so in an elliptical sound field that provides a wide detection range in one plane and a narrow detection range in the other plane.
