🌟 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.

Custom length service 6FX3002-2CT20 – 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 6FX3002-2CT20?

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.
