TONiC Super-compact Optical Encoder

Renishaw’s TONiC super-compact optical encoder provides a solution to a broad range of motion control applications, delivering exceptional signal purity and stability with a low cost of ownership and fast, easy set-up. TONiC optical encoders provide the accuracy of fragile fine-pitch encoders, but in a rugged, simple-to-install package. Advanced optical design and innovative electronics are featured in a compact readhead (35 mm x 13.5 mm x 10 mm L-W-H) for great design/application flexibility and installation even on micro-manufacturing systems for the semi-conductor, lab and medical fields. Enhancing application versatility, TONiC is available in both linear and rotary versions. Supporting many applications from standard motion control to ultra-high precision stages, TONiC offers speeds to a maximum of 10 m/s (3.24 m/s @ 0.1 µm resolution), fine resolution to 5 nm and handles operating temperatures up to 70°C.

Innovative optics with very high ‘signal to noise’ ratio, combined with dynamic signal processing, ensure ultra-low sub-divisional-error (SDE <±30 nm) and jitter. TONiC delivers a level of performance previously available only from more delicate fine-pitch encoder systems. Two integral readhead LEDs give quick and easy set-up and diagnostics, while simple construction using an ASIC and integrated sensor technology brings ‘fit and forget’ reliability.

For ultimate flexibility, TONiC reads a variety of linear and rotary scale types including a new version of Renishaw’s gold scale featuring the auto-phase IN-TRAC™ optical reference mark. IN-TRAC™ provides a bi-directionally repeatable index over the entire speed and temperature range without increasing overall system width. Integral dual limits are also available enabling users to select end of travel position.

With auto-calibration, integral diagnostic LEDs and IN-TRAC optical reference mark, installation could not be easier – TONiC can be set-up and running with maximum performance and minimum fuss in a matter of seconds.
