SIRIUS 3SK today. Achieve machine safety easily

The phase-out of SIRIUS 3TK28 safety relays began in January 2015. These devices will no longer be available for ordering as from October 1, 2018. 

However, this does not apply to the 3TK2810 devices for safe standstill and speed monitoring. These will remain available as usual. To make the conversion to the successful 3SK successor generation as easy as possible, we have summarized information about the conversion on these pages.
