Semiconductor Manufacturing Equipment: The comprehensive braided and foil shielding isolates low-voltage encoder data from the severe electromagnetic interference generated by adjacent high-power frequency inverters.
Frequently Asked Questions
Can this servo cable be used in continuous-flex applications like cable drag chains?
Yes. While our standard offering uses a robust PVC jacket for static routing, we highly recommend selecting our TPE (Thermoplastic Elastomer) jacket option for dynamic, continuous-flex environments. This ensures maximum flex life in robotics and automated drag chains.
How do you guarantee signal integrity for sensitive encoder data in noisy environments?
We construct these cables with double shielding—an aluminum foil layer combined with a high-coverage tinned copper braid. Furthermore, 360-degree shield termination at the connector shells completely isolates the signal from industrial EMI/RFI noise.
What is the Minimum Order Quantity (MOQ) for custom lengths or specific pinouts?
As a direct OEM manufacturer, we support flexible MOQs to help our partners scale from prototyping to mass production. Standard custom runs typically start between 100 to 500 units, depending on specific jacket material and wire gauge requirements.
Are these cable assemblies compliant with international safety and quality standards?
Absolutely. All our servo cables are manufactured and strictly tested under the IPC/WHMA-A-620 Class 2/3 standard. The raw materials used are UL-recognized, CE approved, and fully RoHS compliant for global distribution.
Can I get a drop-in replacement tailored exactly to my Modrol system's wiring diagram?
Yes. By providing your target quantity, specific wiring diagram, or original part number, our engineering team can cross-reference the specifications and manufacture a functional, cost-effective OEM alternative that perfectly mates with your equipment.
Overview and Application Notes
Overview: Engineered for demanding industrial automation environments, this Custom Modrol Servo Encoder Cable Assembly delivers flawless, zero-latency signal transmission between Modrol servo motors and control drives. Manufactured in strict accordance with IPC/WHMA-A-620 standards, it features a specialized 15-pin plug on the motor side and a robust HD15 (High-Density D-Sub) plug on the controller side. Designed with premium tinned copper conductors and comprehensive EMI/RFI shielding, it effectively isolates sensitive encoder data from electrical noise. As a factory-direct OEM solution, EDOM Electronics offers fully customizable cable lengths, pinout mapping, and high-flex TPE jacket options to suit your exact mechanical routing and robotic applications.

Application Notes:
-
EMI/RFI Shielding Integrity: Ensure the cable’s shielding is properly terminated 360-degrees at the HD15 metal shell to prevent signal loss or encoder pulse errors caused by industrial electrical noise.
-
Dynamic Flexing (TPE Option): For continuous-flex applications such as robotic arms or automated drag chains, specify the TPE jacket option and maintain a minimum bend radius of 10x the cable’s outer diameter for flexible routing, and 8x for fixed static installations to prevent premature conductor fatigue.
-
Secure Mating: Utilize the integrated locking screws on the HD15 connector to ensure a vibration-proof connection, preventing accidental disconnections in high-shock CNC environments.
-
Custom Pinout Configurations: While optimized for standard Modrol drives, custom pin mapping is available upon request to accommodate proprietary controllers or legacy automation equipment
