High‑fidelity feedback link for SIMODRIVE · SINUMERIK · Drag chain ready · Wide temperature range · Any custom length
📌 Product overview
The Siemens 6FX3002-2DB20 is a high‑performance encoder feedback cable engineered for SIMODRIVE servo motors и SINUMERIK CNC control systems. It transmits high‑resolution position and velocity signals from the motor encoder to the drive, enabling precise closed‑loop motion control. Built for both static installations и continuous flexing in drag chains, this cable preserves signal fidelity under constant motion, vibration, and electrically noisy environments. A cost‑effective, direct replacement for the original Siemens encoder lead.

🌟 Core benefits
🛡️ Premium EMI shielding – High‑density tinned copper braid blocks electromagnetic interference, preserving encoder signal accuracy and preventing drive communication faults.
🔄 Drag chain certified – Engineered for millions of bending cycles in cable carriers – no signal dropout or conductor fatigue.
❄️🔥 Wide temperature tolerance – -40°C to +105°C with upgraded PVC, ideal for extreme industrial environments.
✂️ Unlimited length options – We supply 6FX3002-2DB20 in exactly the metres you need – no forced stock lengths.
🧵 VDE / IEC fine wire – Class 5/6 stranding gives low bend force and long dynamic flex life.
💰 Smart OEM alternative – Direct electrical and mechanical replacement for the original Siemens encoder cable at lower cost.

Custom length service 6FX3002-2DB20 – any length available.
Unlike fixed Siemens part numbers, we supply this encoder cable in any metre you specify (e.g., 2 m, 3.5 m, 7.2 m, 11 m, 18 m, 25 m … up to 50 m). No large minimum order. Connector can be adapted to your preferred brand.
✅ Why choose our 6FX3002-2DB20?
This encoder cable is not a generic or low‑grade substitute. It fully complies with VDE 0295 / IEC 60228 fine‑stranding rules and features a genuine high‑coverage tinned copper braid – not a simple foil wrapper. This delivers superior signal integrity, excellent noise immunity, and longer service life in moving applications. Every batch is tested for continuity, insulation resistance, and shielding effectiveness. A direct, trustworthy alternative to the original Siemens cable – identical performance, fair price, fast delivery.
