I am trying to buy something and can't seem to describe it well enough to get a good search result.
You know when you buy a wall wart there is the power cord that goes from it to whatever it plugs in to.
It has 2 conductors, or maybe it is coax. I bought one and the cord is so stiff that when I move what it is plugged into, the cord knocks everything off the bench.
I want a flexible silicone cord with 2 conductors (or a coax). It should be 24AWG, and heat resistant if possible. I will solder connectors at each end. But I can't seem to come up with a concise description to work in google or ebay.
Seems like no matter how I describe it I get single wires. Or red & black glued together. I want both conductors insulated and inside an overall insulation, so it looks good. Color doesn't matter.

Any suggestions ?

 

I've looked for silicone insulated two-conductor cable before and never been successful in finding any. I thought I had found some sold as being silicone and intended for use with a tattoo machine. It wasn't silicone (the claims of materials used in stuff from China sold on ebay and the like are very often false). It was quite flexible, but the conductors were light (probably OK for your purposes). The insulation was thick, so overall it was about as large as some 18 AWG "zip cord" I've used. I never tried to solder it, but I suspect it was heavily plasticized PVC and probably would melt easily. There may actually be some with real silicone insulation, but unless you stumble on one that has been reviewed by someone knowledgeable, youse pays yer money and youse takes yer chances.

Small coax can be quite flexible, but many use copper clad steel conductors so the resistance is rather high.

Good quality microphone cable is often quite nice, but it tends to be rather large and moderately expensive.

There are some decent quality single conductor wires with silicone insulation and finely stranded conductors to be had, even on Amazon, in a wide range of gauges. They are nice for test leads.

For some reason, small flexible two conductor zip cord types have disappeared from the market, replaced by stiff annoying junk.

 

Will this help?

It is PVC, so I'm guessing it will be stiff, and not heat resistant.

Virtually the first hit (search for two-conductor silicone "wire") and unfortunately Amazon. That means to me, there are other suppliers..

 

hi,

One of the cheapest suppliers of cord I have found is MonoPrice.
Excellent to deal with.

Yes. As I said, I found Red & Black glued together, but that is not what I want (tho I may have to settle for it).

thanks. I looked at it. It has some downsides and mysteries. From great britain, 1-2 months delivery time. The Mains soldering iron cable is 3 conductor, rated for 3A. The low voltage cable is rated for 5A, but is 5 conductor (sounds fat). None of them are silicone wire, just copper wrapped in silicone insulation.

What do you mean? Are you looking for actual conductors of some sort of silicone composite?

thanks. But it looks as tho they have nothing in silicone.

 

hi pratto,
It would help if we knew your location, so that we could suggest a local source.

no. maybe I misunderstood what the wire data sheet said. it said tinned copper. I took that to mean solid tinned copper wire.
what I am looking for is the silicone wire type that "jpanhalt" linked to. braided or stranded and very flexible.

hi.
Is there a Farnell site in the States.?

That wire that jpanhalt found looks great. I was thinking I'd looked for silicone insulated wire like that within the past year or so, but when I stop and think about it it was probably 5 or 6 years ago. These products seem to have boomed with interest in DIY drones and robotics. It looks like the insulation is co-extruded in the two colors, so the thin bit between the two colors is probably a little ill-defined in terms of color.

The stranding in those wires is very fine, so they are likely very limp.

yes, this is what I was looking for, but newark doesn't have any in stock or close by, and I have to request a quote. I also went to farnell. apparently they are available in britain. besides, it is pretty expensive.

right. just what I want. I guess I'll have to settle for the black and red. ugly.

 

How much temperature are you working with? A lot of PVC insulation is up to 220F rated.
or there is also teflon coated that is high temp too.
