Hub-Shaft Encoders

Similar to hollow-shaft encoders, hub-shaft rotary encoders offer direct mounting to a motor shaft or driven shaft but do not require the shaft to the shaft to extend through the encoder. Hub-shaft encoders are ideal for direct mounting in limited space and offer improved sealing with no opening on the back of the encoder. Hub-shaft encoders are mounted with a tether point to prevent free encoder rotation and a plastic sleeve or insert is typically used to isolate the encoder from motor shaft current.
