TONiC Series Readhead and Interface -- With REXM Angle Encoder

Print Print

The DSi combined with the new ultra-high accuracy REXM ring offers new levels of angular metrology¦

  • When REXM is used with DSi it offers better than ±1 arc second total installed accuracy
  • Non-contact system locks to the rotor to eliminate 'reversal errors' and coupling losses 
  • The REXM ring features a thick cross-section to minimise all installation errors except eccentricity
  • Eccentricity is eliminated using the DSi which means that the only errors remaining are graduation and SDE, both of which are exceedingly small
