Rated output is 0.4 kW at 3000 r/min, making it a fit for indexing, pick-and-place, and light assembly axes where rapid acceleration and compact motor dimensions matter. The motor includes an oil seal (J designation), which extends bearing life in environments where cutting oil or lubricant mist is present — common on machining-center tool changers and transfer lines. Without that seal, oil ingress shortens MTBF on the encoder and bearings. ## Integration note The MR-JE-_A amplifier uses a general-purpose interface (A type), meaning it accepts pulse-train and analog speed/torque commands from a motion controller without a dedicated fieldbus card. The HG-KN43J-S100 motor ships with the oil seal fitted; verify the mating connector and encoder cable length match your existing harness layout before racking the amplifier.","metaTitle":"Mitsubishi MR-JE-40A+HG-KN43J-S100 Servo Amplifier & Motor,","metaDescription":"Mitsubishi MR-JE-40A+HG-KN43J-S100 servo amplifier and AC servo motor combo, 0.4 kW rated output, 3000 r/min rated speed, with oil seal.
