INTRODUCTION
Our PUR high flexible servo feedback encoder cable is fully interchangeable with Siemens original 6FX5002, 6FX8002 MOTION-CONNECT 380/800 series signal wires. Designed for precise position, speed and temperature signal transmission between SINAMICS drives and SIMOTICS servo motors, this double-shielded cable adopts VDE Class 6 extra-fine copper strands for millions of drag chain reciprocating bends. We support pre-molded M23 / 25pin D-Sub connectors, custom length, pinout and sheath material, perfectly matching incremental, absolute, DRIVE-CLiQ & EnDat encoder protocols. All cables pass CE, RoHS, DESINA and ISO9001 industrial standards.Matching Siemens Original Part Numbers

PUR Feedback Cable vs Siemens OEM PVC Cable
| Parameter | Our PUR Siemens Compatible Feedback Cable | Siemens OEM PVC Fixed Cable |
|---|---|---|
| Drag Chain Suitability | Excellent (10M+ bend cycles) | Only static laying |
| Oil/Chemical Resistance | Superior | Weak, easy swelling |
| Low Temp Flexibility | -40℃ no cracking | Brittle below -10℃ |
| Outer Sheath Material | Polyurethane PUR | PVC |
| Dynamic Service Life | 3–5x longer | Short lifespan for moving axes |
| Cost | 60%-75% of official Siemens price | High original factory price |
Q: Is your cable a direct replacement for Siemens 6FX8002-2CA31?
A: Yes, identical pinout, core layout, electrical parameters and green PUR sheath, fully plug-and-play for 1FK7/1FL6 servo motors and SINAMICS S120/S210 drives.
Q: Can this feedback cable run inside drag chains continuously?
A: Our PUR 6FX8002 equivalent model is designed for dynamic drag chain operation with 10 million bending cycles; 6FX5002 PVC version for fixed installation only.
Q: What connectors do you pre-assemble for Siemens systems?
A: Standard M23 straight/angled plug, 25-pin D-Sub connectors; we support custom crimped or molded connector assembly.
Q: Will incompatible feedback cable trigger Siemens drive fault codes?
A: Our balanced twisted pairs and double shielding ensure stable differential signals, effectively avoiding F31111, F31112 encoder signal errors on SINAMICS drives.
Q: Do you offer free samples for Siemens system testing?
A: Yes, 1m–5m free test samples available for factory verification, bulk wholesale factory direct pricing.
