The 3M brand Wiremount Socket, 451 Series draws on over five decades of 3M Company’s expertise in insulation displacement contact technology. The heart of the socket is the unsupported cantilever U-contact. It is made of Beryllium Copper, an alloy which provides a combination of low stress relaxation, good overall reliability, and long service life for secure connections and signal integrity. Customers can choose between 30μ” gold and gold flash platings in the wiping area for multiple mating/unmating cycles at different price points to suit their engineering requirements and budget. Compared to crimping or soldering, IDC offers a quick and cost-effective way to terminate many wires by hand, and without the need for automatic or semi-automated equipment.
