Allen-Bradley 845G-F3D8HC1000A Absolute Encoder

Allen-Bradley 845G-F3D8HC1000A is a 24V optical absolute encoder with a 3/8" shaft and a 25 mm square flange for rigid mounting in industrial control gear. This single-turn device delivers 12-bit, binary-coded-decimal position feedback with a 0–999 counts-per-revolution scale, enabling precise angular measurement within automation systems. It uses a 24V DC supply and provides High True, open-collector style outputs via a 19-pin axial interface, making it compatible with common Rockwell/Allen-Bradley signaling and I/O schemes. The encoder is housed to meet NEMA 4/13 enclosure ratings for use in harsh factory environments and is part of the 845G family known for reliable single-turn absolute feedback in industrial automation.
