Allen-Bradley 842E-CM-MIP2BA Absolute Encoder

The Allen-Bradley 842E-CM-MIP2BA Ethernet/IP Absolute Encoder is a CIP Motion-enabled feedback device for EtherNet/IP control networks. It provides true absolute position data with multi-turn capability, delivering 18-bit, 262,144 steps per revolution and up to 4,096 turns of memory to track position across power cycles. The encoder uses a solid 3/8 in shaft with a flat for secure coupling and an M12 field-wiring connector for rugged industrial environments. As a member of the 842E-CM family—Integrated Motion on EtherNet/IP—it serves as a non-contact axis feedback solution for motion controllers and servo drives, enabling precise, repeatable positioning in automation applications such as robotics, CNC machines, and packaging lines. With Ethernet/IP communications and CIP Motion support, it facilitates straightforward integration into Rockwell Automation architectures, delivering fast, deterministic position data to improve control performance and reliability.
