Safety Radar Systems
The LBK S/SBV refers to a system within the Safety Radar Systems product category, primarily used for safety applications.
Description and Explanation
The LBK S/SBV system utilizes radar technology for Detection of movement and Detection of persons. It meets high safety standards, designated as Performance Level (PL) d according to EN ISO 13849-1, and SILCL 2 in accordance with IEC 61508 and EN IEC 62061. Its safety Category according to EN ISO 13849-1 is 2 or 3.
These radar sensors operate in demanding environments, with an operating ambient temperature range of -30 to 60 °C. The sensors have an overall response time of 100 ms.
The LBK safety radar sensors, along with a controller, are referenced as components in safety solutions, such as Access monitoring at a material transfer station, where they monitor the area between multiple light beam safety devices for the presence of persons.
