The New Low Cost LIKgo Linear Encoder

NUMERIK JENA is proud to introduce the LIKgo, a newly designed linear encoder especially developed to fit customer demands for use in production and inspection machines in the semiconductor industry. LIKgo is NUMERIK JENA’s next generation of incremental exposed linear encoder. It is very compact and extremely easy to install with generous mounting tolerances thanks to a new scanning technology providing improved signal quality. Due to this new two-field scanning principle, the signals are produced free of offset errors and phase errors. The measuring standard is a newly developed SINGLEFLEX steel scale tape with a width of only 8 mm and a grating period of 20 µm. 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 78.125 nm is possible. Next to the incremental track runs a reference track with reflecting reference mark and an information track containing the serial number.

Other advantages and benefits of this new LIKgo include a very small scanning head that weighs only 5 g. The scanning technology is especially resistant to contamination thus very reliable, and the electronics produce very low heat. Other applications include linear drives, coordinate measuring machines and measuring microscopes.More products
