Multipin Connectors

Multipin Connectors Used in High and Ultra High Vacuum Environments

MPF manufactures Multipin Connectors with a single header design and varying conductor qualities. These multipin’s are typically used for the transmission of multiple electrical signals. In some applications, they could also be used for low power requirements. The pin sizes can vary from .032” inches up to .142” inches supporting 1 amp per pin to 40 amps per pin. We offer these designs in Copper, Alumel, Nickel, BeCu, Stainless steel, and Molybdenum conductor materials. We offer instrumentation circular Mil-C-5015 and Mil-C-26482 in addition to Instrumentation rectangular Sub D series 24308 and Micro D series 83513.
