Allen-Bradley 844D-B6CC4FW is a hollow-shaft incremental optical encoder from Rockwell Automation that provides precise rotary position feedback for automation and motion-control systems. It delivers 1024 pulses per revolution and uses a 10-pin connector with differential line-drive outputs, operating from a DC supply in the 8–26 V range with 5 V logic on the outputs. This model features a 3/4 in hollow shaft, enabling straightforward slip-on mounting on a mating shaft, and offers tether option C for added safety in demanding or high-vibration environments.
