Innovative USi-safety ultrasonic sensors for factory automation

The Pepperl+Fuchs innovative USi-safety ultrasonic sensor system is a modern and certified sensor technology that is employed 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 system protects people and objects from possible dangers and collisions. This ultrasonic sensor assures the safety of personnel and takes its place in the field of electro-sensitive protective devices.

The ultrasonic sensor system, claimed to be the only kind globally, is characterised by its flexibility and a broad range of applications. Up to two small, freely positionable ultrasonic sensor units may be positioned, connected, and parameterised flexibly and geometrically regardless of the electronics. The safety function is offered with only one sensor unit, i.e., with no redundancy. They can be integrated into restricted spaces and reliably identify moving and stationary objects with any shape, colour, or surface in an elliptical, three-dimensional sound field of up to 2.5m. Dirt, airflow, temperature, and humidity have no impact on the function of the sensor. This makes it an exceptional selection for almost all applications in the industry and outdoors. The sensor system is set up employing convenient parameterisation software. Each connected sensor unit is provided with two short-circuit and cross-circuit-monitored OSSD safety outputs. A teach-in function for teaching in the entire detection area as a standard environment increases operational safety. This function suppresses vehicle contours that produce disturbance, for example.
