The unit is available in North America through parent company Heidenhain Corp. Common applications for open linear encoders are stages for medical and semiconductor machines, as well as miscellaneous metrology applications.
Open, non-contact linear encoders are increasingly used in applications that require higher traversing speeds and operating cycles, as well as lower mechanical backlash and zero frictional force induced by an encoder. The RSF MS 25 linear encoder fills this bill and with permanent control of the scanning signals over the whole measuring length. The tricolored LED allows for easy mounting because it needs no test box or oscilloscope, and is helpful for quick troubleshooting during operation.
The encoder uses a single-field scanning principle which allows for traversing speeds to 10 m/s, large mounting tolerances, and insensitivity to contamination on the scale. Interpolation electronics are built into the encoder’s head allowing resolutions from 10 µm to 100 nm. Two end-of-travel optical switch signals are also available directly out of the reader head. The user can set the end travel signal locations.
