Renishaw Intros Super-Compact Encoder
Super-compact encoder.
Hoffman Estates, IL — New from Renishaw, the TONiC super-compact encoder provides a refreshing solution to a broad range of motion control applications, delivering exceptional signal purity and stability with a low cost of ownership and fast, easy setup. Advanced optical design and innovative electronics are featured in a compact readhead (35 x 13.5 x 10mm) for great design/application flexibility and installation.

Enhancing application versatility, the new encoder is available in both linear and rotary versions. Supporting many applications from standard motion control to ultra-high precision stages, it offers speeds to a maximum of 10 m/s (3 m/s at 0.1µm resolution), fine resolution to 5nm and handles operating temperatures up to 70°C. According to the company, innovative optics with very high signal-to-noise ratio, combined with dynamic signal processing, ensure ultra-low sub-divisional-error (SDE <±30nm) 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, the encoder reads a variety of linear and rotary scale types including a new version of the company'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.
