Encoder Mounting

G-option mounting ears
  • Mounted to non-reciprocating portion of base
  • Needs to be centered on rotating shaft
public/Detailed Design Documents/Encoder Subsystem/Mounting1.png
E-option cover
  • Allows extra shaft clearance
  • Keeps moving parts covered
public/Detailed Design Documents/Encoder Subsystem/Mounting2.png

Sensing Shaft

  • must be centered on a self-supporting shaft
  • shaft must introduce minimal friction
  • mount support shaft under static base
