Linear Encoder

NUMERIK JENA’s Low-Cost LIKgo designed for the semiconductor industry.

May 23, 2019   by DE Staff

NUMERIK JENA introduced the LIKgo, a low-cost linear encoder. The sensor employs a two-field scanning principle that produces signals free of offset errors and phase errors. The measuring standard is a SINGLEFLEX steel scale tape with a width of 8mm and a grating period of 20µm. The interpolation and processing of the signals takes place inside the scanning head, thereby eliminating the need for additional electronics in the connector. Measuring steps down to 78.125nm are possible. Next to the incremental track runs a reference track with a non-reflecting reference mark. Other advantages include a small scanning head that weighs 5g. The scanning technology is resistant to contamination, due to its relatively large scanning windows.
