Allen-Bradley 845T-DB13ECS Incremental Encoder Series B This item was purchased from a large business inventory reduction sale. I do not know the history of it. It is in good cosmetic condition except that there is a small ding around the edge of the terminal threads (see the last three pictures). It actually looks like a cable would still thread on with not much effort. The shaft spins very easily by hand. I am not able to test it further. It only comes with what is shown in the pictures.
