Tri-Tronics Hollow Shaft Encoder
Hollow shaft encoders are designed with either a through-bored shaft or a blind-bored shaft, and intended to mount directly onto a motor or other shaft. This eliminates the need for a shaft to shaft coupling and mounting adapter, resulting in both space and cost savings. The encoder "floats" on the motor shaft. A tether or flexible mounting bracket prevents the encoder from turning, yet accommodates shaft-to-shaft misalignment.
