Ultrasonic safety sensor system

26 April 2021

Pepperl+Fuchs is expanding its ultrasonic sensor range with the addition of the USi-safety ultrasonic sensor system.

The sensor was developed to safeguard hazard areas on mobile machines such as robots, industrial trucks, machines, and plants according to EN ISO 13849-1 category 3 PL d. The USi-safety system protects people and objects from potential dangers and collisions. This ultrasonic sensor ensures the safety of personnel and takes its place in the range of electro-sensitive protective devices.

Up to two small, freely positionable ultrasonic sensor units can be positioned, connected, and parameterised flexibly and geometrically, regardless of the electronics. The safety function is provided with only one sensor unit – without redundancy. They can be integrated in confined spaces and can reliably detect moving and stationary objects with any shape, colour, or surface in an elliptical, three-dimensional sound field of up to 2.5m. Dirt, temperature, air flow, and humidity have no impact on the function of the sensor.
