Product Description
The Mitsubishi MR-J3-PWS5-79-20M is a 20-meter shielded servo motor power cable, designed for 3 kW and 3.5 kW HG-SP/HG-JP motors, offering high flexibility, easy straight-connector installation, and reliable performance in moderate (0C to 55C operating, -20C to 75C storage) and harsh (IP67-rated) environments by resisting electrical interference, dust, and water immersion.
Is Your Device Showing These Signs?
The Mitsubishi MR-J3-PWS5-79-20M cable frequently exhibits issues such as insulation degradation leading to short circuits, connector pin corrosion causing signal loss, and cable jacket damage from abrasion or excessive bending which interrupts power transmission. Technicians address these problems by replacing damaged conductors, cleaning or replacing corroded connector pins to restore proper connectivity, and reinforcing or replacing the cable jacket to prevent further environmental damage and ensure reliable servo amplifier operation. Shielding integrity is verified to mitigate electromagnetic interference (EMI) affecting positional accuracy. Continuity testing confirms proper wiring and prevents drive malfunction.
