Shafted vs. Hollow Shaft Rotary Encoders.！

shafted rotary encoder is built so that the rotor portion of the encoder is a short shaft that is usually attached through a flexible coupling to the shafts of various motion control equipment. The body of the shafted rotary encoder is commonly fixed by a rigid mounting bracket.

hollow shaft rotary encoder is composed in a way so that the rotor portion of the encoder is tubular, with the inner diameter of the rotor tube sized to accept and clamp to most standard shaft sizes. This style does not require the use of a coupling, however, the body of the rotary encoder must be constrained by a flexible tether arrangement. Hollow shaft encoders are available in two configurations: through-shaft and blind-shaft. .
