The version for absolute wire draw encoders has SSI, Profibus, CANOpen or DeviceNet interfaces, and the version for incremental wire draw encoders has an HTL or TTL interface. It fits any 60mm servo-mount encoder.

Additional features include stable spring return, highly flexible steel rope and steel dirt removers that help reduce wear and increase product life.

The MRA-F works by way of drum rotation, which is proportional to the length being measured. This movement is counted by an encoder and converted to a measuring signal, providing high-resolution position or distance information for linear measurement paths, even under difficult ambient conditions.
