Pepperl+Fuchs USi-safety ultrasonic sensor features EN ISO 13849 category 3 PL d certification.

Pepperl+Fuchs introduced the USi-safety ultrasonic sensor, designed for use in harsh environments and outdoor applications. With safety certification in accordance with EN ISO 13849 category 3 PL d, the USi-safety is a 2-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 2500mm. 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 successfully used just above the floor or close to a wall. Due to the opening angle of ± 17°/± 5°, a particularly wide detection range is generated in one plane and a narrow detection range in the other plane.
