FAQ
Q: What is this cable used for?
RS485 communication in industrial automation, control systems, PLC networks, and data acquisition - anywhere a stable 100Ω link is required over long runs.
Q: What does "overall shielded" mean?
The whole cable is wrapped in Al/PET foil plus a tinned copper braid. This blocks electromagnetic interference from motors, drives, and other equipment on the factory floor.
Q: Do you offer custom lengths and marking?
Yes. Standard lengths run from 100m to 1000m. Custom drum sizes, cable lengths, and print marking are available - tell us your requirements.
Q: Can I get samples before ordering?
Yes. Send us your specifications and we will confirm sample availability, cost, and lead time. Sample charges can be discussed based on order volume.
Q: What is the MOQ and lead time?
MOQ depends on cable type and length. Typical production lead time is 7–15 working days after order confirmation. Contact us for a specific quote.
Q: Can you print our brand or part number on the cable?
Yes. Custom print marking is available - your brand, part number, or specification text. Send us the exact wording before production.
