Choosing an RS-422 cable
RS-422 sends each signal as a differential pair, which makes it far less sensitive to noise than RS-232 and allows much longer runs. A basic link uses two pairs: one to transmit and one to receive.
How many pairs?
Two pairs for a 4-wire link. Add pairs for handshake signals or when several links share one cable.
Which shield?
An overall foil is the basic shield. Foil plus braid gives more protection in electrically noisy areas. Individually shielded pairs reduce crosstalk between the pairs.
RS-422 or RS-485?
RS-422 is mainly used point to point or with one transmitter and several receivers. RS-485 allows many devices to share one pair and calls for 120 ohm cable; those are on our RS-485 page.
Why Belden?
- Low-capacitance 100 ohm pairs for long serial runs
- Beldfoil shield with full coverage
- Overall, individual and combined shield constructions
- PVC, LSZH and plenum-rated jackets
- A datasheet for each code on belden.com

Frequently asked questions
Which Belden cable is used for RS-422?
Belden lists its low-capacitance paired computer cables for RS-422: the 8102 series with foil and braid, the 9729 series with individually shielded pairs, and plenum and LSZH versions.
Can I use RS-422 cable for RS-485?
RS-485 networks are normally specified with 120 ohm cable, while these pairs are 100 ohm. For RS-485 use the cables on our RS-485 page.
Is there a halogen-free RS-422 cable?
Yes. Belden lists LSZH types such as 8104ELW, 9503NH and 9503ELW in this category.
Do I have to buy a full reel?
No. We supply cut lengths. The part number and the total length are enough.
Request a quote
- If you know the code: the part number, total length and delivery country are enough.
- If you do not: send your application, line length and environment; we recommend the type.
- If you have a specification or BOQ: send it and we will return the matching part numbers.
