The safeRS and safeRS3 safe radar systems are electro-sensitive 3D protective devices for safe personal detection with very high machine productivity. They protect applications in accordance with PL d or SIL 2 in line with ISO 13849-1 and IEC 62061. A radar system consists of an evaluation unit and up to 6 sensors which enable switchover to a protected mode as soon as a person enters the protected area. The high resistance to dirt, dust clouds, wood chips, plastic particles and sparks as well as the insensitivity to ambient light such as solar radiation or infrared waves enables reliable operation, even under the toughest ambient conditions. The radar systems stand out due to their rugged sensor housing and quick and easy commissioning.
