Circular Connectors – Electronic Parts Sourcing

Circular connectors are multi faceted pin connectors that are used mainly for external interfacing. They are often utilized for electrical signal transmissions, powering electrical devices and data transfers. They can also be used to carry and transfer mixed signals.

Connector Types

There are various types of connectors including circular metal shell connectors (CMC), military (mil-spec) connectors, DIN connectors, etc. The CMC, along with the circular plastic connector, is OEM designed, meaning that the plug and the receptacle are often configured to mate solely with their own exclusive connectors. The shell size, type and coupling arrangement ensure that insertion of connectors made for other applications do not connect. 

Military connectors (MIL-SPEC) are designed based on their military specifications, the design of which takes into account the need to shield the connector from outside environments as well as the need to make them withstand military conditions. DIN connectors are multi-pin, high frequency electrical connectors that are designed based on the standards established by the Deutsches Institut für Normung (DIN), a German national organization for standardization. The ends of these connectors are round, notched, and protected by a metal skirt to guarantee the pins line up accurately. Along with these connectors, there is also the micro and nano connectors. These demonstrate contact pitches of 0.05" (micro) and 0.025" (nano), respectively, with one or more straight or right angled plated contacts.
