Mitsubishi MR-J3ENCBL5M-A2-H ENC Cable New

MR-J3ENCBL5M-A2-H | Mitsubishi MR-J3 Encoder Cable — 5m / A2 Connector / High-Flex / Shielded / RoHS / Servo Feedback

MR-J3 Encoder Cable — Closing the Servo Loop

The MR-J3ENCBL5M-A2-H is Mitsubishi Electric's pre-assembled encoder cable connecting the MR-J3 servo amplifier's encoder input to the servo motor's encoder output — the feedback link that enables the MR-J3 to perform closed-loop velocity and position control. Without this cable, the amplifier has no position or speed data from the motor, making closed-loop servo operation impossible.

The "-A2-H" designation identifies two critical properties: the A2 connector type at the motor end, and the high-flexibility (H) cable construction for installations where the cable must flex during motion.

Key Specifications

A2-Type Connector — Secure Motor-End Connection

The A2 connector designation identifies the specific motor-side interface:

Tight, secure fit: The A2 connector uses a positive locking mechanism — when fully engaged, the connector locks against accidental disconnection from vibration, axis travel, or incidental contact. This is the "A2-type connector ensures tight, secure fit" property confirmed in the product specification.

MR-J3 motor compatibility: The A2 connector mates with the encoder socket on specific MR-J3-compatible servo motor models — the motor's encoder connector format determines which cable type (A, A2, B, etc.) is required. Always confirm the motor encoder connector type before specifying the cable.

Plug-and-play installation: The MR-J3ENCBL5M-A2-H arrives pre-terminated at both ends — A2 connector at the motor, amplifier-side connector for the MR-J3 CN2 encoder input. No field connector assembly is required.

Applications

MR-J3 CNC machine tool axis drives: Feed axis servo motors on Mitsubishi CNC (MELDAS/M70/M700 series) machine tools using MR-J3 amplifiers — the standard encoder feedback cable for each servo axis.

MR-J3 industrial robot axes: Mitsubishi RV-M series and related industrial robots using MR-J3 servo systems for joint axis position control.

MR-J3 servo positioning systems: General-purpose servo positioning in automated assembly, inspection, and material handling equipment — any MR-J3 installation with A2 encoder connector motors.

Dynamic servo axis applications: Servo axes with cable track-routed encoder cables — the high-flex construction handles continuous cable track flexing that would cause standard cables to fail prematurely.

FAQ

Q1: What is the difference between MR-J3ENCBL-A2-H (standard) and MR-J3ENCBL-A2-L (long-distance or low-loss)?

Within Mitsubishi's MR-J3 encoder cable range, different suffix codes identify specific cable variants. Confirm the exact suffix differences (H vs L, and the number vs letter in the last character) from Mitsubishi's MR-J3 servo amplifier connection guide — each suffix encodes the cable construction type, connector variant, and application compatibility. Always match the cable to the specific amplifier and motor combination confirmed from Mitsubishi's documentation.

Q2: Does the encoder cable type (A, A2, B) depend on the motor or the amplifier?

The connector type at the motor end depends on the servo motor model — different motors use different encoder connector formats (A, A2, B, etc.) based on their size class and encoder type. The amplifier-end connector (CN2) is standard across all MR-J3ENCBL variants. Confirm the correct motor-end connector from the motor's nameplate or Mitsubishi's servo motor cable selection guide — using the wrong connector type results in a cable that cannot mate with the motor encoder socket.

Q3: Can MR-J3ENCBL5M-A2-H be used with MR-J4 amplifiers?

MR-J3 encoder cables are specific to the MR-J3 amplifier's CN2 encoder interface. The MR-J4 amplifier uses a different encoder interface (DRIVE-CLiQ or MR-J4 specific connectors) — MR-J3 encoder cables are not directly compatible with MR-J4 amplifiers. For MR-J4 installations, Mitsubishi specifies the corresponding MR-J4 encoder cable variants.

Q4: What length variants are available for MR-J3ENCBL-A2-H?

Mitsubishi's MR-J3ENCBL-A2-H series is available in multiple standard lengths including 2m, 3m, 5m, 10m, 20m, and longer options. The "5M" in the part number identifies the 5-metre variant. Select the length appropriate for the actual cable routing distance from servo amplifier CN2 connector to motor encoder socket, with reasonable service loop allowance at each end.
