Siemens 6FX3002-2DB20 Encoder Cable

High‑fidelity feedback link for SIMODRIVE · SINUMERIK · Drag chain ready · Wide temperature range · Any custom length

📌 Product overview

Le Siemens 6FX3002-2DB20 is a high‑performance encoder feedback cable engineered for SIMODRIVE servo motors and 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 and 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.

✅ 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.
