The safeRS and safeRS3 safe radar systems are electro-sensitive 3D protective devices for safe personal detection with very high machine productivity. According to ISO 13849-1 and IEC 62061, they cover stationary applications in accordance with PL d or SIL 2. An assessment unit and up to 6 sensors make up a radar system, allowing for the switchover to a protected mode as soon as a human enters the protected area. Even in the harshest environmental conditions, reliable operation may be achieved thanks to the strong resistance to dust, wood chips, plastic particles, and sparks, as well as the insensitivity to ambient light such as solar radiation or infrared waves. The robust sensor housing and rapid and simple commissioning make the radar systems stand out.
