The IP67-rated enclosure means the motor body handles washdown and airborne particulates directly on the machine frame — no secondary cover needed. That's a real advantage on food, beverage, or packaging lines where hose-down cleaning is routine. Inside, the 22-bit absolute encoder gives 4,194,304 pulses per revolution, shared between absolute and incremental modes. That resolution supports tight position hold without homing on power-up, as long as the battery-backed absolute system is maintained. For a line-down swap, the encoder type matches the J4 drive's native feedback interface — no adapter or converter board between the motor and the servo amplifier. The acceleration ratings tell you what the mechanical build can handle: X-axis 24.5 m/s², Y-axis 49 m/s². The Y-axis figure is roughly 5 g, so this motor can drive a vertical axis or a fast pick-and-place Z motion without oversizing the frame. The recommended load inertia moment ratio of 15 times or less is the practical tuning boundary — stay inside that and the J4 auto-tuning will converge without oscillation. The standard build ships without an oil seal. If the application mounts the motor with the shaft pointing down into a gearbox or a wet zone, order the HG-SR_J variant with the oil seal option — that keeps lubricant from migrating along the shaft into the encoder or winding. The vibration class is V10, which is the standard level for general industrial servo duty; no special dampening required for most conveyor, rotary table, or linear-axis builds.","metaTitle":"Mitsubishi HG-SR352BJK Servo Motor, MELSERVO-J4, 200V, IP67","metaDescription":"Mitsubishi HG-SR352BJK servo motor from the MELSERVO-J4 series. 200V class, IP67 enclosure, 22-bit encoder, acceleration ratings X: 24.5 m/s² Y: 49 m/s².
