October 25, 2010 - RSF announces the MS 25A open linear encoder (no housing on scale) equipped with a integrated mounting control. The encoder utlizes a tricolored LED directly at the reading head enabling the user to gage if the mounting and subsequent measurement readings are optimal. Common applications for open linear encoders are stages for semiconductor machines, as well as miscellaneous metrology applications.Open, non-contact linear encoders are increasingly being used in measurement 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 fits this bill and offers permanent control of the scanning signals over the whole measuring length. The use of the tricolored LED allows for easy mounting since no test box or oscilloscope is needed, and is helpful for quick troubleshooting during operation.The RSF MS 25 utlizes a unique single-field scanning principle which allows for high traversing speeds (up to 10 m/s), large mounting tolerances and insensitivity to contamination on the scale. Integrated into the head of the MS 25 encoder is a wide range of interpolation electronics enabling resolutions from 10 µm to 100 nm. Two end-of-travel optical switch signals are also available directly out of the reader head. The end travel signal locations can be easily set by the user.The buyer can also choose from six mounting configurations for the graduation, as well as from various substrate options for the tape and carrier. And due to recent advancements in technology, all of these benefits are now available in a small package design.
