Linear Encoder for Semiconductor Industry



NUMERIK JENA offers the LIKgo, a low-cost linear encoder designed to meet the demands for use in production and inspection machines in the semiconductor industry. It is available in North America through HEIDENHAIN Corporation.

"The new LIKgo is the next generation of incremental exposed linear encoder from NUMERIK JENA," said a company spokesperson. "It is extremely compact and easy to install with generous mounting tolerances due to a new scanning technology that provides significantly 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 SINGLEFLEX steel scale tape with a width of 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 are possible. Next to the incremental track runs a reference track with a non-reflecting reference mark.

"Other advantages and benefits of this new LIKgo include a very small scanning head that weighs only 5 g," added the spokesperson. "The scanning technology is resistant to contamination due to the relatively large scanning windows, and is thus very reliable." The electronics produce very low heat due to low current consumption.

Other applications for the LIKgo encoder include linear drives, coordinate measuring machines and measuring systems.

NUMERIK JENA is part of the HEIDENHAIN group, and is based in Jena, Germany, with North American representation and distribution through HEIDENHAIN Corporation.
