RSF Open Linear Encoder

A new open linear encoder (no housing on scale) equipped with a unique integrated mounting control is now available from RSF. Called the MS 25, this RSF encoder utlizes a tricolored LED directly at the reading head enabling the user to gage if the mounting and subsequent measurement readings are optimal. It is available in North America through parent company HEIDENHAIN Corporation. 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 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.

AMO Corporation’s new IP67-Rated LMB-410 Spar Linear Encoder

AMO Corporation (www.amo-inc.com) is proud to announce the release of the new IP67-rated LMB-410 Spar Linear Encoder, which will be spotlighted at the 2010 International Manufacturing Technology Show (IMTS) at McCormick Place, Chicago on September 13 to 18. The company’s stall will be found in Booth #E-5220 inside the Quality Assurance Pavilion located in the Lakeside Center (East) Building.

The new LMB-410 offers robust measuring/position feedback with IP-67 rating and performance similar to a linear optical encoder. The LMB-410, operating on an inductive scanning principle, is best suited for general purpose machines, such as medical equipment, printing equipment, machine tools and military/aerospace applications. Its IP67 rating makes the machine ideal for dirty or contaminated conditions including being fluid submersible.

Its adhesive-free mounting spar with a snap cover eliminates concerns related to adhesive-backed spars becoming loose in oily environments. Its encoder head is equipped with wipers to automatically clean spar scale during operation. The encoder head’s gain compensation and auto offset eliminate the need to use a test box during setup.

The LMB-410 is rated for operation that ranges from -40 to +120°C for any measuring length ± 5 micron/m linearity. The new encoder also meets high-shock, high-speed and vibration specifications.
