Description

V2BJW30D20F is a standard Renishaw VIONiC readhead with a 3 m cable length. This readhead is configured for rotary encoder system using RESM20 rings with outer diameters >; 135 mm.

The VIONiC incremental encoder readhead, when combined with the RESM20 ring, offers highly reliable digital position feedback for superior metrology, smooth motion control due to low sub-divisional error (SDE), and high axis speeds.

V2BJW30D20F Key Features / Benefits:

V2BJW30D20F rotary encoder is compatible with RESM20 rings (diameters >; 135 mm)
V2BJW30D20F features a reference mark and a 3-state alarm output
V2BJW30D20F features a highly dynamic 3 m cable with a 15-way D-type connector cable termination (standard pin out)
V2BJW30D20F requires a controller input frequency of at least 20 MHz

About the VIONiC series of super-compact digital encoders:

Renishaw’s highest performing incremental optical encoder is easy to install with wide set-up tolerances and simple calibration
VIONiC readheads combine Renishaw's market proven filtering optics, dynamic signal control and advanced interpolation technology. This provides ultra‑low SDE, excellent dirt immunity, and eliminates the need for separate interfaces
An optional Advanced Diagnostic Tool ADTi-100 (A-6195-0100) is available for real‑time encoder data feedback during installation or for in-field diagnostics
A CAD model of the VIONiC readhead is available from the Renishaw website
