Leine Linde Systems has introduced a new slip ring with integrated, functionally safe encoder. Their solution enables an efficient speed monitoring design and meets design demands for manufacturers at the same time.
In the newly developed FSR product range, a modular slip ring that can be customised to meet specific customer demands is combined with a functionally safe rotary encoder. This also includes a secure interface for a subsystem of the safety control. The rotary encoder used in the FSR and the communication master (part of the subsequent electronics) are certified according to DIN EN ISO 13849 or EN 61508 for PLd or SIL 2. If additional measures are implemented in the subsequent electronics, PLe or SIL 3 can also be achieved.
