Technical

Industrial automation requires monitoring of speed-relevant limits such as maximum and minimum speed, standstill or rotational direction. Baumer speed monitors come into play where system safety and reliability come under very demanding safety criteria. When it comes to the safety of man and machine, in particular, the speed monitors of the GMM series meet the most stringent requirements on maximum safety by twin certification compliant to DIN 61508 and ISO 13849.

SIL3 / PLd speed monitors support functional safety implementation, for example at
