Renishaw: TONiC™ TD (dual resolution) encoder system-TD0400A50A

TD (dual resolution) interface

Selectable dual-resolutions quadrature output.

Ideal for applications that require high speed movement combined with finer precision motion

Renishaw’s TONiC series encoders are now available with simultaneous dual output interfacing. The robust DOP interface can be situated up to 10 m from the TONiC readhead and offers simultaneous analogue and digital outputs with interpolation to 1 nm resolution. Digital outputs are clocked for optimised speed performance at all resolutions for industry-standard controllers. The readhead is compatible with a wide range of linear, partial arc 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
