Siemens 6FX3002-2CT20 Encoder Cable
Siemens 6FX3002-2CT20 Encoder Cable
Precision feedback lead for SIMODRIVE motors · SINUMERIK CNC · Drag chain ready · Wide temp range
📌 Product overview
Le Siemens 6FX3002-2CT20 is a high‑integrity encoder feedback cable designed for SIMODRIVE servo motors and SINUMERIK CNC controllers. It securely carries position and velocity signals from the motor encoder back to the drive, ensuring precise motion control. Engineered for both fixed installation and continuous flexing in drag chains, this cable maintains signal fidelity even under constant motion, vibration, and electrical noise. A direct, reliable replacement for the original Siemens encoder lead.

🌍 Extreme‑climate capable: Choose the upgraded heat/cold‑resistant PVC jacket and this encoder cable maintains clean feedback signals from -40°C freezers to +105°C machine compartments.
📐 Bend radius guidelines
| Installation scenario | Min. bending radius (× cable OD) |
|---|---|
| Fixed / static routing | 6 × OD |
| Moving stroke < 10 metres | 7.5 × OD |
| Moving stroke ≥ 10 metres | 10 × OD |
🌟 Why this encoder cable stands out
🛡️ High‑density tinned copper braid – Blocks EMI/RFI interference, preserving encoder signal accuracy and preventing drive communication errors.
🔄 Drag chain certified – Withstands millions of bending cycles in cable carriers; no signal dropout from conductor fatigue.
❄️🔥 Wide temperature window – -40°C to +105°C with upgraded PVC, ideal for cold storage, outdoor, or high‑heat zones.
✂️ Any length you need – We supply 6FX3002-2CT20 in exactly the metres required – no forced stock lengths.
🧵 VDE / IEC fine wire – Class 5/6 stranding gives low bend force and long dynamic flex life.
💰 Smart OEM substitute – Direct electrical and mechanical replacement for the original Siemens encoder cable at better value.

✅ Why choose our 6FX3002-2CT20?
This encoder cable is not a generic or low‑grade alternative. 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 means superior signal integrity, excellent noise immunity, and a longer service life in moving applications. Every batch is tested for continuity, insulation resistance, and shielding effectiveness. A direct, trustworthy substitute for the original Siemens cable – identical performance, fair price, fast shipping.
