mixed contact Amphenol MC4012D AA connectors featuring gold plated contacts and multiple shell sizes
Positronic Combo-D D-Sub Connectors
Product Overview
Positronic Combo-D D-Sub connectors offer versatile interconnect solutions by allowing mixed contact combinations of power, shielded, air, high voltage, signal, and thermocouple contacts within a single connector body. Available in standard and high-density configurations across six shell sizes, these connectors are designed for professional, industrial, and military applications, providing three performance levels for optimal cost-performance ratio. They feature precision machined contacts, robust construction, and various termination options including solder, straight and right-angle printed board mount, and compliant press-fit. Applications range from general electronics to demanding environments requiring high reliability and mixed signal/power capabilities.
