Frequently Asked Questions
Are these encoder cables suitable for use in continuous-flex drag chains?
Yes. For drag chain (C-Track) applications, we strongly recommend choosing our PUR (Polyurethane) jacket option. Built with highly stranded conductors and specialized insulation, these cables are tested to withstand over 5 million flexing cycles in dynamic environments.
How do you ensure the cable prevents EMI/RFI interference with the encoder signals?
We use a robust dual-shielding design consisting of an aluminum Mylar foil and a high-density tinned copper braid (with over 85% coverage). This effectively blocks both low and high-frequency noise generated by adjacent power cables or factory equipment.
Can you manufacture these cables with specific custom lengths or angled connectors?
Absolutely. As a direct OEM manufacturer, we can produce cable assemblies to your exact specifications, including custom lengths, specific wire labeling, and right-angle (90-degree) overmolded connectors for space-constrained installations.
Do these assemblies undergo high-voltage and continuity testing?
Yes, every single cable assembly is 100% factory tested before shipment. Our quality control process includes rigorous continuity tests for correct pinouts, as well as Hi-Pot (High Potential) testing to ensure there are no short circuits or insulation failures.
What is the Minimum Order Quantity (MOQ) for custom OEM servo cables?
We provide flexible MOQs designed to support our B2B partners. Whether you need a small batch for machine prototyping or high-volume mass production, please contact our engineering team to discuss your specific requirements.
Overview and Application Notes
Overview Engineered for high-precision industrial motion control systems, our CM-SP10S-L Servo Encoder Cable Assemblies provide zero-latency absolute position feedback for Mitsubishi MR-J3, MR-J4, and MR-JE series servo motors. Manufactured in our ISO-certified facility, these assemblies utilize high-flexibility, multi-stranded copper conductors and heavy-duty tinned copper braided shielding to ensure absolute signal integrity even in extreme EMI environments. Available with rugged PUR (Polyurethane) jackets, these cables are specifically rated for millions of cycles in continuous-flex drag chain applications. Fully compliant with IPC/WHMA-A-620 standards, we offer factory-direct OEM/ODM manufacturing to provide custom lengths, specialized pinouts, and tailored connector overmolding for your specific robotic or automation projects.
Application Notes
-
Drag Chain (C-Track) Installation: For continuous dynamic flexing applications, rigorously maintain a minimum flexible bend radius of at least 10x the cable’s outer diameter (OD), and 8x OD for fixed installations. Ensure cables are laid flat in the track without twisting to maximize lifespan.
-
EMI Separation: Never route this sensitive encoder signal cable in the same conduit or closely parallel to high-voltage servo power cables or Variable Frequency Drive (VFD) output lines. Always maintain standard physical separation to prevent induced electrical noise.
-
Shield Grounding: Ensure the cable’s braided shield is properly terminated 360-degrees at the servo amplifier end to provide a low-impedance path to ground, effectively rejecting high-frequency noise that could cause encoder counting errors.
