The Allen-Bradley MPL-B420P-SJ22AA is a Kinetix MPL low-inertia permanent magnet servo motor for 400 V-class drives in the 115 mm frame, rated 1.9 kW at 5000 rpm with 4.74 N·m continuous stall torque and 13.5 N·m peak stall torque. This version has a 1024 sin/cos absolute single-turn encoder (Hiperface), a keyed shaft without shaft seal, no holding brake and an IEC metric mounting flange. The code "2" in the connector position is not listed in the current Rockwell catalog number key, so please confirm that part of the configuration against the motor nameplate. Rockwell designs the MPL range for high-performance motion systems such as packaging, converting, material handling and electronic assembly, with a high torque-to-size ratio and IP50 protection as standard without a shaft seal.
