The MITSUBISHI MELSERVO-J4 SERVOMOTOR 200W HG-KR23J is a state-of-the-art rotary servo motor engineered for demanding motion control tasks. Featuring a 23-bit high-resolution absolute encoder, this motor delivers exceptional feedback accuracy and eliminates the need for homing routines on startup. Its compact frame (40 mm flange) and lightweight design make it perfect for space-constrained installations. With a rated torque of 0.64 Nm and a maximum torque of 1.9 Nm, the HG-KR23J excels in applications requiring rapid acceleration and deceleration, such as pick-and-place units, assembly robots, and high-speed labeling systems. The integrated electromagnetic brake ensures fail-safe operation, while the IP65 protection rating (shaft end excluded) guarantees reliability in industrial environments.
