TONiC™ is Renishaw’s new super-compact non-contact optical encoder that offers speeds up to 10 m/s and resolutions down to 5 nm for both linear and rotary applications. Offering significant enhancements to Renishaw’s existing range of high speed non-contact optical encoders, TONiC™ also gives improved signal stability and long-term reliability, low cost of ownership and unrivalled simplicity.

Motion system designers usually face a compromise between speed and accuracy. With the TONiC™ optical encoder, this dilemma is removed and even at resolutions as low as 0.1 µm offers speeds in excess of
3 m/s, across a variety of linear and rotary scale types. This includes a new version of Renishaw’s flexible gold tape scale which features the highly regarded customer selectable IN-TRAC™ optical reference mark, which is auto-phased simply by the press of a button. Uniquely, the IN-TRAC™ reference mark is directly embedded into the incremental channel, which maximises immunity to yaw-induced de-phasing and furthermore, ensures phasing is retained throughout the entire speed and temperature range.

Renishaw’s range of optical industrial encoders is widely recognised for giving machine builders fast and easy installation. In addition to the INTRAC™ bi-directional reference mark, the new TONiC™ encoder takes this simplicity to the next level by offering auto-calibration and a readhead with two integral diagnostic LEDs.

The new TONiC™ readheads may be small, but signal purity and stability are further enhanced by incorporating dynamic signal processing within the readhead, providing an ultra-low Sub-Divisional Error of better than ±30 nm.
