Home > Products > Suspension Wire

Replacing beryllium copper is a new material "Suspension Wire", a very promising alloy alternative utilizing its ultrafine ( minimum diameter, 0.030mm ) providing outstanding stability of OIS in smartphones.

*Whiscut® is a trademark of TOTOKU Electric Co., Ltd.

Features

  • Superior straightness ( -pat 3786256- ) based on cutting edge technology and advanced process and design development at TOTOKU.
  • Available either on reels and or as cut to length.
  • Products are pre-spooled on reels for a ready-to-use product.
  • We also provide Beryllium-free technical support.
  • We also provide Ultrafine ( minimum diameter, 0.030mm ) technical support.
  • We also provide different types of plating support for surface treatment.
  • We are able to provide samples (prototypes) to mass production, through faster lead time solutions from raw material to production.
  • We also provide mass production for 0.001mm units.

Applications

It has been widely used to support optical components from optical pickup to camera module and etc. And recently, due to the growth in smartphone usage. Suspension wire has established itself as one of the key components for the wire type under the built-in camera OIS system.

Its superior characteristics of straightness makes it suitable and desirable for precision cuts in mass productions. Hence increasing yield and production rate, especially in automation of production for reels.
