Small metal bobbin wound with thin stainless steel conductive thread

Adafruit

Adafruit Stainless Thin Conductive Thread 2 ply 23m 76ft

SKU CH-84HY-YDGP9

Stainless-steel conductive thread for wearable circuits, 23 m on a bobbin, 16 Ω/ft to power LEDs under 50 mA without oxidising

  • Product typeEngineering Development Tools
  • 76ft length supports extended wearable projects
  • 316L stainless steel construction prevents oxidation over time
  • 2-ply thread at 0.2mm thickness enables hand or machine sewing
  • 16 ohms per foot resistivity drives LEDs under 50mA
  • 3 ohms per inch allows low-power circuit integration

Wearable conductive thread

Adafruit stainless thin conductive thread is a 2-ply spool designed for e-textile and wearable projects. It suits makers who need a sewable electrical path for low-current circuits. The 316L stainless steel construction avoids the oxidation problems common with silver-coated alternatives.

Resistivity limit

The thread measures 1.3 ohms per inch, or 16 ohms per foot, which restricts it to components drawing under 50mA such as small LEDs. Builders needing higher current capacity for motors or dense LED arrays cannot meet that requirement with this thread.

Sustained sewing behaviour

Because the material is strong and smooth, it resists fraying during extended hand or machine stitching sessions. The 0.2 mm thickness feeds reliably through medium-eye needles without snapping, and the stainless steel does not degrade with handling over long project timelines.

Questions about this item

What does 16 ohms per foot mean when I sew a circuit?

At 16 ohms per foot the thread adds noticeable resistance; it will power LEDs and small components drawing under 50 mA but voltage drop limits longer runs.

How does the 316L stainless steel construction affect the connection?

316L stainless steel will not oxidize like silver-plated thread, so the conductivity stays stable through washing and wear.

Will the 0.2 mm 2-ply thread fit through a standard sewing machine needle?

The 0.2 mm thickness works in medium-eye hand needles and in machines rated for heavy thread; test a scrap first to confirm tension.
