Mitsubishi MR-J4-20B Servo Drive – 0.2kW, 200V

The Mitsubishi MR-J4-20B is a precision-engineered digital AC servo amplifier from the compact and high-performance MELSERVO J4 series, ideal for motion control in electronics assembly, light robotics, and compact automation systems. Designed for single-phase or three-phase 200–240V AC input, this model supports up to 0.2 kW rated output power with 1.5 A current draw, while communicating via SSCNETIII/H — Mitsubishi’s ultra-fast fiber-optic servo network. Its natural cooling system (fanless), IP20 housing, and integrated Safe Torque Off (STO) safety function make the MR-J4-20B a cost-effective and reliable option for small-scale, safety-critical automation.
