Allen-Bradley 845H-SJHM24DRY2C Industrial Servo Drive

Allen-Bradley 845H-SJHM24DRY2C is an incremental encoder (Bulletin 845H) used to provide precise position feedback for servo drives and motion controllers in automation systems. Designed for servo applications, it features a 3/8-inch shaft, an English servo flange, and a radial side connector with a mating connector for straightforward integration in compact assemblies. It operates from an unregulated 8–24 V DC supply and delivers 5000 pulses per revolution via RS-422 differential line-driver (DLD 5 V) signaling, making it compatible with common motion-control interfaces. This variant is listed as discontinued by the manufacturer, reflecting its availability primarily on secondary markets while maintaining the essential Bulletin 845H feedback characteristics.
