The key features of the boardmount header are highlighted here. The two rows of gold plated phosphor bronze pins arranged in a 1.27 mm grid are housed inside a molded insulator of liquid-crystal polymer (LCP). This material has good mechanical strength at high temperatures, extreme chemical resistance, and inherent flame retardency rated at UL94V-0. A centerbump slot ensures the 451 Series socket is the correct way around before mating. Optional latches help to keep the connectors mated in use or easily ejected for repair or maintenance. For details of the header’s electrical performance ratings, see the 3M tech sheet number 78-5100-2437-1 available from 3Mconnectors.com.
