Position encoders

If you design or manufacture machinery, then speak to Renishaw to ensure that you maximise your competitive offering – from dragsters to rotary tables, we have encoders to speed up your performance and your development processes. 

DSi (Dual SiGNUM™ interface)

Precision rotary axes often demand very high accuracy without calibration or error-map. The DSi allows the addition of a second readhead to eliminate odd error harmonics including eccentricity and compensate for the effect of both static and dynamic bearing wander. The result is total installed error of typically ±2.0 arc second (209 mm diameter RESM).

SiGNUM™ Si-FN interface with FANUC serial communications

SiGNUM™ FANUC - all the benefits of Renishaw’s SiGNUM™ range of intelligent encoders... now with FANUC serial communications!

The non-contact format and large through-hole of the RESM ring, combined with high accuracy and a rugged IP64 sealed readhead make SiGNUM™ encoders perfect for machine tool rotary axes. The new Si-FN interface adds FANUC serial communications.

REXM high accuracy angle encoder

For applications that require the highest angular accuracy, the REXM angle encoder offers new levels of angular metrology - better than ±1 arc second total installed accuracy, zero coupling losses and exceptional repeatability.

Like Renishaw's RESM ring encoder, the REXM stainless steel ring has graduations marked directly onto the periphery. However, it features a thicker cross-section designed to minimise all installation errors except eccentricity.
