Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: DEV-11791. This plated silver type thread tarnishes easy so we've replaced it with stainless steel instead, go check it out! This page is for reference only.

Description: Conductive thread is a creative way to connect various electronics onto clothing. This thread can carry current for power and signals. While not as conductive as traces on a printed circuit board (PCB), this thread makes wearable clothing 'wearable'!

This is a plated silver type thread (as opposed to stainless steel). This is a thicker thread with a lower resistance that can be used with hand sewing. Resistance is about 14 Ohms per foot. Spool contains 1oz of thread, about 75 yards.

Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.

  • Manufacturer (I think): Shieldex-US

    Datasheet (234/34 4ply):
    http://www.shieldextrading.net/pdfs/260151023534oz.pdf
    At first I was inclined to say just use AWG standards for current per wire diameter. However I haven’t had much luck melting copper with a lighter. This thread melts quite well. I, too, was hoping to find a “don’t exceed this” on the datasheet.

  • hi sparkfun,
    a recent order of this thread turned out to be the old hairy stuff you discontinued a few years ago. is this product no longer the “new and improved” thread?

  • I also would like to know the power limit of this thread. Any one has a schematic for heating circuit, please let me know. Thanks

    • if you want to make a heating circuit, probably this product is better:

  • I also want to know about using this wire as a heating element for electric gloves…

    • Molten plastic upon you if it warms ~enough~! Beware!
      Don’t let the wires cross! (You’ll shorts and lose your resistance.)
      Watts heat made = (amps2)50feet of thread.

  • I’d also like a datasheet.
    Is this thread exposed such that crossed threads will short?
    Or is it insulated and I’ll need to remove insulation to make an electrical connection?

  • I agree with the above poster… I really like the idea, but data sheet please!!! :-)

  • What kind of power limitations does this thread have? i.e.- could it be used as a conductive thread heating element in a jacket liner?
