Allen-Bradley 845G-F3GAHS032KU Incremental Encoder

Allen-Bradley 845G-F3GAHS032KU is an optical single-turn absolute encoder from Rockwell Automation that provides a deterministic shaft-position reading within a single rotation rather than relative increments. It operates on 10–30 VDC and uses Gray-code output to present a 15-bit position value (0–32,767 counts per revolution). The unit features a Size 20 housing with a 3/8 in shaft diameter and a radial 12-pin connector, and it carries a NEMA 4/13 enclosure rating for rugged industrial environments. This encoder is designed for motion-control and automation applications requiring reliable, reference-free position feedback across power cycles, such as servo drives, CNCs, robotics, and packaging equipment. The single-turn 15-bit code provides precise, repeatable position readings within each revolution, simplifying decoding in control systems and enabling quick startup without homing. With its absolute encoding and rugged form factor, it is well suited for harsh factory settings where accurate position data is crucial for precise motion control.
