Industrial Servo Wiring Solution – Mitsubishi MR-J3CN1 | MR-J3 Series
Where This Product Is Used
The Mitsubishi MR-J3CN1 is the OEM-specified signal connector designed exclusively for the MR-J3 series servo amplifier lineup. It is widely deployed across the following industrial environments:
- CNC Machining Centers – Precision axis control wiring between servo amplifier and controller
- Automotive Assembly Lines – High-cycle servo motion systems requiring reliable signal integrity
- Packaging Machinery – Multi-axis servo coordination in form-fill-seal and cartoning equipment
- Semiconductor Fab Equipment – Clean-room compatible servo signal termination
- Injection Molding Machines – Servo pump and clamp axis signal interface
- Robotic Welding Cells – Servo drive signal harness termination points
Wherever a Mitsubishi MR-J3 series amplifier is installed, the MR-J3CN1 is the correct mating connector for the CN1 signal port.

Application-Specific FAQ
Q: Is the MR-J3CN1 compatible with MR-J4 series amplifiers?
A: No. The MR-J4 series uses a different CN1 connector specification. Please verify your amplifier model before ordering.
Q: Does this connector include the shell and strain relief?
A: The MR-J3CN1 is the OEM connector assembly. Please confirm the exact kit contents with our sales team for your specific application.
Q: Can I use a third-party connector instead?
A: Mitsubishi Electric specifies the MR-J3CN1 for all CN1 wiring. Third-party substitutes may compromise signal shielding and void amplifier warranty.
Q: What wire gauge is recommended for CN1 signal wiring?
A: Mitsubishi recommends shielded twisted-pair cable, AWG 24–28, for CN1 signal connections. Refer to MR-J3 Series Servo Amplifier Instruction Manual for full wiring specifications.
Q: Do you offer technical support for MR-J3 system commissioning?
A: Yes. Contact our engineering support team at [email protected] for application guidance.
