TONiC™ encoder series
The TONiC™ series is a compact, non-contact incremental encoder system that offers speeds up to 10 m/s and, when combined with the Ti interface, resolutions down to 1 nm for both linear and rotary applications. Advanced filtering optics within the readhead give TONiC very low jitter, resulting in excellent positional stability and smoother velocity control. This makes TONiC the ideal encoder for applications where movement must be tightly controlled.
The TONiC encoder also features exceptional signal stability with low Sub-Divisional Error (SDE) to help realise superior motion control performance. TONiC systems feature an integrated set-up LED for intuitive and efficient installation. They are compatible with Renishaw's ADTpro-100 diagnostic tool.
Additionally, the TONiC™ encoder series offers a variety of external interfaces that can be configured to meet the speed and resolution requirements of the application. With late-stage integration and configuration of the external interface, one versatile TONiC readhead offers many options for end user customisation.
Very low jitter for stable machine positioning
The TONiC™ encoder series features Renishaw's market-proven filtering optics and advanced signal processing. Auto Gain Control (AGC) and Auto Offset Control (AOC) technologies reduce analogue signal noise and digital jitter within the readhead. TONiC encoders deliver exceptionally low signal output jitter of <±0.5 nm RMS and low Sub-Divisional Error (SDE) of <±30 nm, enabling systems to hold position better and generate less heat in linear motor applications.
Fine resolution down to 1 nm
When combined with the optional Ti interface, the TONiC™ encoder series offers ultra-fine resolution down to 1 nm. This capability makes TONiC the ideal choice for applications requiring precise velocity and positional control, especially in low speed applications.
Ultra-High Vacuum and Functional Safety variants
The TONiC™ encoder offers a single solution for various applications, with the same exceptional metrology capability offered by TONiC UHV, for Ultra-High Vacuum applications, and TONiC FS, for systems requiring Functional Safety certification to SiL2 and PLd.
