Allen-Bradley 845H-SJDZ13-CKY2-C Rotary Encoder

Allen-Bradley 845H-SJDZ13-CKY2-C is an optical incremental rotary encoder that provides 360 pulses per revolution (360 CPT) for precise speed and position feedback in automated systems. It operates from a 5 V DC supply and outputs via an NPN current-sink configuration, suitable for interfacing with PLCs and motion controllers. The device uses a side radial connector and features a square-flange mounting arrangement for secure installation in tight spaces. A 3/8 inch diameter shaft matches common servo and motor assemblies. This 845H model is part of the 845H family of incremental encoders, designed for reliable, low-noise signaling in industrial environments. Typical applications include conveyors, packaging lines, automated assembly cells, and other motion-control tasks where accurate rotational feedback is essential, enabling precise speed control and positional tracking across automated production workflows.
