Mitsubishi SC-J2SJ4ENC03M Encoder Conversion Cable for MR-J2S to MR-J4 Renewal

The Mitsubishi SC-J2SJ4ENC03M (SC-J2SJ4ENC03M) is an encoder conversion cable set for replacing MR-J2S series servo amplifiers with MR-J4 series amplifiers while retaining the existing MR-J2S encoder cable. It is a 30 cm signal conversion cordset that connects on the amplifier side and terminates in a servo amplifier connector. The cable is compatible with MR-J2 and MR-J4 series equipment and is equivalent to SCJ2SJ4ENC03M. Mitsubishi identifies it as an A-type encoder conversion cable and lists it under renewal kit MR-J2S-A/B to MR-J4-A/B applications. It is intended for A-type MR-J2S to MR-J4 replacements at 11 kW and above when the original J2S encoder cable remains in use. The assembly weighs approximately 0.183 kg and carries material number 271231. Typical use is in servo drive upgrades and maintenance projects where the amplifier is changed but the existing encoder wiring is kept, reducing rework. This is a specific interface accessory for Mitsubishi MELSERVO systems, not a general-purpose cable. Verify the amplifier model, replacement type and encoder-cable retention plan before ordering.
