Rectangular MIL Spec Connectors are a type of electrical connector commonly used in the military and aerospace industries. They are typically used to connect electrical and electronic components such as resistors, transistors, and ICs. These connectors have varied sizes, shapes, styles, and pin configurations which can depend on the application or use. Certain types are also built to meet specific environmental requirements as well. The key characteristics of these connectors include durability, tamperproof, solderability, and EMI shielding capabilities. Rectangular MIL Spec Connectors come with a variety of contact options, such as crimp, stamped, and machined contacts, as well as hermetic seals for humidity and dust resistance.
