Encoders

The AFM60 absolute multiturn encoder from Sick Stegmann has improved ruggedness and 30-bit resolution. Its smaller brother, the AFS60 absolute single-turn encoder, provides a resolution of 18 bits.

The AFM/AFS60 incorporate a nickel code disk, which given the same resolution, is more robust than code disks made of glass. Compared to plastic code disks it offers better resolution and higher temperature resistance — the AFM/AFS60 can be used at ambient temperatures of from -20 to +100 °C. In addition, the expanded 30 mm shaft bearing of the AFM/AFS60 ensures considerably greater ruggedness than encoders with blocked ball bearings.

Each device in the AFM/AFS60 series, with industrial rated 60 mm housings, is available as a clamping or a servo-flange version for solid round shafts. Users can choose between M12 and M23 plug connections, or opt for cable exits that can be used radially or axially with various connector lengths. This reduces the number of different variants and simplifies installation when space is limited.

Both the AFM60 and the AFS60 have an SSI interface and can be programmed using the same programming tool.
