Small wire harness

Swh2

SWH™ is made from litz wires, twisted together to small wire harnesses. With the unique construction of the twisted litz wires gathered in a "bunch", the SWH™ is much stronger and more stress resistant than individual litz wires.

  • Cost-savings
    Handle and solder all litz wires in one operation instead of two to three.
  • Fewer claims
    Get a more reliable product with the stress resistant construction of the SWH™.
  • EMI improvement
    Get the positive effect from twisted wires. Use one conductor as ground.
  • Space saving
    Benefit from the "stronger" construction and use finer wires than usual.
  • Small, extremely reliable, colour coded and very easy to handle in production. SWH™ will improve your yield - and contribute to fewer returns from the market.

We also offer a higher level of subassembly, such as feeding the small wire harness into tubes, soldering terminals to the SWH™ in addition to performing custom operations; also for earphones and IEMs.

Applications: Hearing Instruments, earphones/IEMs and other micro electronics

  • Receiver In the Canal: SWH™ is ideal for applications where wires need to fit securely inside a tube. Available in skin colour, which makes the SWH™ discrete.
  • In The Ear/In the Canal: Perfect for microphones, receivers etc. The conductors are held together in a harness, which is easily placed inside of the earplug. It is no longer necessary to twist the wires together after soldering the receivers and microphones.
  • Behind The Ear: After soldering the SWH™ to the components, the SWH™ is easily placed and secured into position.
