RSF Elektronik Offers the Smallest Sealed Linear Encoder

February 23, 2015

RSF Elektronik recently developed the MSA 170, a small, full-sealed linear encoder for motion feedback. The MSA 170 has a scale cross section of 14 mm x 10 mm and contains a glass scale to carry the measuring graduation.

Available in North America through parent company Heidenhain Corporation, the MSA 170 is suited for motion applications in various industries such as manually-operated machine tools, metrology, semiconductor, medical and automation. The MSA 170 can also be found in CNC applications where limited space and proper testing has been completed by the machine builder.

The MSA 170 features a graduation of 20 micron and a scanning carriage that operates on the principle of reflected light. The optics are protected from contamination by an aluminum extrusion and sealing lips. The scanning carriage is guided along the extrusion and the glass scale by means of ball bearings. The glass scale is also available with one, multiple or distance-coded reference marks that are bi-directionally repeatable to one count of the final resolution.

The encoder electronics are integrated in the scanning unit and are available with either 1 Volt Peak to Peak or digital TTL output signals with a resolution to 0.1 micron. The maximum measuring length is 520 mm and accuracy grades of + 5 micron or +3 micron are available.
