Amphenol CBD2WK2M0000ZAA mixed signal power and shielded connector with precision machined contacts
Product Overview
Positronic's Combo-D series connectors offer a versatile solution for mixed signal, power, shielded, air, and high voltage contact requirements within a single connector body. Available in standard and high-density configurations across six shell sizes, these connectors are designed for reliability and performance in various environments. They feature precision machined contacts, including options for open entry or PosiBand closed entry signal contacts, and Large Surface Area (L.S.A.) female power contacts for enhanced mating surfaces and reduced resistance. The series supports multiple performance levels (professional, industrial, military) to suit different cost/performance ratios and applications, including options for blind mating and sequential mating.
