Renishaw's VIONiC line features two readhead variants and is available with metal tape, spar, and rotary rings scale types.
Renishaw’s all-in-one digital incremental encoder VIONiC range has been designed to reduce overall system size to the minimum achievable for a high-performance system. The line features two VIONiC readhead variants. The standard VIONiC readhead features a Sub-Divisional Error (SDE) of <±30 nm, a range of available resolutions from 5 µm to 20 nm, and speeds beyond 12 m/s. The VIONiCplus features SDE to <±10 nm, low jitter to 1.6 nm RMS and resolutions from 100 nm down to 2.5 nm. Low SDE encoders are essential to minimize velocity ripple, which is important in constant-velocity applications such as laser scanning. VIONiC series encoders are available with the same linear and rotary (angle) scale ranges as the TONiC series. Available scale types include metal tape, spar, and rotary rings (including ultra-high accuracy REXM). All VIONiC scales come with customer selectable IN-TRAC reference marks embedded in the incremental channel and dual-limit switches in the case of linear scales.
