RSF Electronics offers a wide range of enclosed and open linear encoders, and rotary encoders. The enclosed models are best suited for harsh environments, with extra protection (IP 64) available for very harsh environments. They feature resolution from 5 µm to 0,1 µm. The non-contact open encoders have resolution ranging from 10 µm to 0,05 µm.Depending on the version of the measuring system, two different measuring scales are available: glass (partially ROBAX glassceramic) or steel. They offer several rotary encoder series, features of some of these systems include up to 7.200.000 counts per revolution.
