SIAMEZE IDC terminals interconnect copper and aluminum magnet wires

Our SIAMEZE insulation displacement (IDC) terminals are engineered for interconnecting copper and aluminum magnet wires, lead wires, and other components. Our SIAMEZE IDC terminal technology eliminates the need to strip the film insulation from copper and aluminum magnet wires and lead wires. Our terminals are available in wire-to-wire, Lead Lok, quick disconnect tabs, posts, pin, and receptacle terminals. Our new IDC terminals enable use with aluminum magnet wire providing design flexibility and potential material cost savings.

SIAMEZE Terminals for Al Magnet Wire

For motor manufacturers, there is an increasingly popular trend to move from copper to aluminium magnet wire due to the lower cost and weight of aluminium magnet wire versus copper. Our new SIAMEZE terminals for Al Magnet Wire are designed specifically for use with Al magnet wires. 


Key Benefits:

  • Eliminates the need for welding or soldering processes, improving operating and manufacturing efficiencies
  • Space saving size for small motor designs
  • No pre-stripping of wires needed saving time and labour costs
  • Available in various interconnection options providing design flexibility

Product Overview

SIAMEZE Terminals

Available with either Moving Beam contacts whereby a single terminal connects to a very wide range of magnet wire sizes, or a Compliant Beam for contacting two magnet wires of the same diameter in one terminal for splicing or bi-filar applications. Tab terminals are available with single barbs or multiple retention barbs for higher retention. According to TE specifications SIAMEZE cavities are either integrated into coil bodies or specially designed cavity housings. The magnet wires are positioned in the “U” shaped slots. The SIAMEZE terminal inserter cuts the terminals from the strip and places the terminals over the magnet wire into the plastic cavities. During this operation the small stripping devices penetrate the film insulation from the magnet wire.


Residual spring energy in the terminal causes the side walls of the IDC slot to function as opposing cantilever beams. This constant pressure results in an intimate metal-to-metal interface, providing a reliable, long-term connection. The wiping action between the wire and terminals remove all oxides or other contaminants present on both the conductor and the terminal slot side walls, producing a clean, stable, gas-tight electrical termination. The SIAMEZE terminal inserter may be used as a semi-automatic bench machine or integrated in production lines for fully-automatic applications.
