Armel now supplies the 8-pin Kelvin sockets that Tyco Electronics' CII division uses in the production of certain of its relays. Tyco approached Armel to develop an 8-pin Kelvin socket to replace the machined sockets from multiple soruces that Tyco had been using. Those sockets, according to Armel, exhibited quality problems and slowed down relay production. The machined sockets were neither rugged nor reliable enough to keep production running smoothly; some would suffer mechanical failures after just one or two tests.
After examining samples, Armel developed a transfer-molded Kelvin socket that has proven to be rugged and reliable, the company says, adding that repeated line-testing operations have been failure-free. Armel now supplies 8-pin Kelvin sockets, like the one pictured on the bottom of this page, to Tyco. A source from Tyco confirms the use of Armel's Kelvin sockets in production of the company's "half-f" and LS relays.
Armel's Kelvin sockets are designed to mil-spec standards and are among a family of products Armel makes available to defense and commercial industries.
