Mil Spec Circular Connectors

Mil (or military) spec circular connectors are a type of electrical connector made to meet the toughest of requirements in harsh environments.


What are mil spec circular connectors used for?

Originally designed to meet military specifications, mil spec circular connectors are used in rugged environments in automotive contexts, mobile equipment, and oil and gas applications. They are specially designed for durability and resistance to vibration, corrosion and so on depending on the application.
