Renishaw: TONiC™ encoder system T2xxx rotary readhead T2021-50A

Renishaw’s TONiC series is designed for highly dynamic precision motion systems, bringing higher accuracy, speed and greater reliability to a wide variety of demanding industry sectors.

The readhead is compatible with a wide range of linear and rotary scales with bi‑directional optical IN-TRAC ™ reference marks.

For ultimate reliability and high dirt immunity, TONiC readheads incorporate Renishaw’s market proven filtering optics, tuned for even lower noise (jitter), further enhanced by dynamic signal processing including Auto Gain Control (AGC) and Auto Offset Control (AOC). The result is ultra-low Sub‑Divisional Error (SDE) giving smoother velocity control for improved scanning performance and increased positional stability.

TONiC readheads also feature a detachable analogue or digital interface in the form of a robust, convenient connector that can be located up to 10 m from the readhead. The interface offers digital interpolation to 1 nm resolution, with clocked outputs for optimized speed performance at all resolutions for industry‑standard controllers.
