Traditional optical encoders
Not recommended for new designs
The RG2 and RG4 incremental encoder systems have a strong reputation established over many years for providing reliable and robust position feedback for a wide variety of applications. However, Renishaw is continually developing innovative incremental and absolute encoder technologies and our latest encoder systems offer a range of additional benefits including enhanced metrology, smaller package size, easier installation and detailed diagnostics. Therefore, the RG2 and RG4 series are not recommended for new designs.
EVOLUTE is a true absolute non-contact optical encoder with a 50 μm scale period that gives enhanced installation tolerances and greater dirt immunity for high-volume applications that demand the highest operational integrity. Using a scale period of 50 μm gives EVOLUTE a generous 500 μm rideheight tolerance and its single track optics are optimised for contamination resistance.
