Mitsubishi MR-J3-HC2SB-50M: IP65 Rated Servo Motor Cable

Connect your servo motor to its drive reliably over long distances. The Mitsubishi MR-J3-HC2SB-50M is a dedicated 50-meter servo cable. It is designed for 1kW and 1.5kW motors in the HC-LP, HC-RP, and HC-UP series. This cable includes all necessary power, feedback, and brake wires in one robust, IP65-protected jacket.

Detailed Technical Specifications

• Product Model: Mitsubishi MR-J3-HC2SB-50M (MELSERVO J3 Series Accessory).
• Cable Length: 50 meters.
• Motor Compatibility: For HC-LP, HC-RP, and HC-UP series motors (1.0 kW and 1.5 kW).
• Protection Rating: IP65 (Dust-tight and protected against water jets).
• Connectors: Straight connectors on both ends (motor side and amplifier side).
• Wire Configuration: Includes conductors for main power, encoder signal, and electromagnetic brake.
• Operating Temperature: -10°C to +60°C.
• Shielding: This specific cable model is unshielded.
• Cable Weight: Approximately 11.34 kg.

Installation & Usage Notes

• Application: Ideal for connecting servo drives to motors in machine tools, packaging equipment, and material handling systems.
• Installation Environment: Suitable for use in areas requiring protection against occasional washdown or dust.
• Routing Consideration: Due to its length and weight, ensure proper support and strain relief when routing the cable to prevent connector damage.
• Electrical Noise: As an unshielded cable, it is best used in environments with low electromagnetic interference (EMI). For high-noise areas, a shielded variant is recommended.

Packaging & Support Details

• The cable is supplied coiled and packaged to prevent damage during shipping.
• This accessory product is covered by a standard warranty.
• We ship worldwide using reliable carriers like FedEx, UPS, and DHL.

Expert FAQs

• Can I use this cable with a 2kW or larger HC series motor?
  No. This cable is specifically rated for the current and wire gauge required by 1kW and 1.5kW motors. Using it with a higher-power motor could cause overheating and is a safety hazard.
• What is the consequence of using an unshielded cable in a noisy plant environment?
  Electrical noise from nearby drives, welders, or radio sources can interfere with the low-voltage encoder signals, causing communication errors, erratic motor behavior, or drive faults.
• Does the IP65 rating mean the connectors are also waterproof?
  The cable jacket and the connector backshell are designed to meet IP65. However, the integrity also depends on the mating connector on the motor and drive being properly rated and securely mated. Always check the mated pair's specification.
• Why are dedicated servo cables used instead of separate wires?
  Dedicated cables ensure correct wire gauge, pairing, and twisting for power and encoder signals. This minimizes electrical noise pickup (crosstalk) and voltage drop, which is critical for stable servo performance, especially over 50 meters.
• Can I cut and re-terminate this cable if I need a shorter length?It is not recommended. The connectors are factory-molded. Cutting and re-terminating requires specialized tools and knowledge to maintain the IP rating and electrical characteristics. It's better to order the correct length.
