Sell instrumentation cable, pairs and all.
Shielded pairs and triads from labs, process plants and central offices, where pair count and shield integrity carry the review.
Instrumentation cable carries signals rather than power, which makes it lighter, thinner and easier to overlook in a clear-out. It is also the cable most often thrown away by mistake, because a partial reel looks insignificant next to a feeder.
In the Richardson and semiconductor corridor, and in process plants across the Metroplex, these reels accumulate in instrument rooms and labs until someone decides the shelf needs clearing.

01 Construction
Pairs, triads and shields
Most of this cable is built from twisted pairs, individually or overall shielded, with a drain wire for termination. Triads appear in temperature work, and thermocouple cable uses specific conductor alloys rather than copper.
Pair count, shield type and conductor alloy are the three facts a buyer records first. Everything else is secondary.
- Individual and overall shielded pairs.
- Triads for resistance temperature work.
- Thermocouple cable with alloy conductors, identified by type.
- Drain wires, often tinned or stranded.
02 Quantity
Lengths that look small but are not
A 500 ft reel of 20 AWG pairs weighs very little, so it is easy to dismiss. On footage and pair count it can still be a useful lot, particularly where several reels from the same project are kept together.
Where the tag is gone, the reel is measured by wraps and the print is read for pair count. It takes longer than a THHN reel, which is why photographs of the print matter here.
Keep reels from the same project together. A set of matching instrumentation reels reviews better than the same reels separated across a warehouse.
03 Sources
Labs, plants and central offices
Lab fit-outs produce clean partial reels. Process plants produce pulled lengths, sometimes with the shield cut back at the ends. Telecom rooms produce their own shielded cable alongside grounding copper.
FAQ Seller questions
What sellers ask before they send a list
Answers describe how the buying desk works. They are not an offer, a rate or a promise of purchase.
Is small-gauge instrumentation cable worth collecting?
Yes, when there is footage and pair count to review. Several reels from one project are the usual way a small-gauge lot becomes worth a collection.
Do you buy thermocouple cable?
Yes, where the alloy type is identified. Thermocouple cable is not copper cable, so the type has to be read from the print or the tag.
What if the shield is cut back at the ends?
That is normal for pulled cable. The review looks at how much of the shield remains continuous and whether the drain wire is intact.
Can instrumentation cable go in a mixed lot?
Yes. It is listed as its own line with pair count and footage, and kept separate from power cable in the description.
