Product Overview

CN Series Connectors

Aptiv Interconnect's CN Series connectors deliver robust and reliable interconnect solutions engineered for heavy-duty, environmental usage in demanding applications across diverse sectors including process and control, marine, oil and gas, machine tools, industrial machinery, power distribution systems, transportation, and military/aerospace. Characterized by their durable construction and often featuring threaded or bayonet coupling mechanisms, these connectors have been designed to meet or exceed the electrical performance requirements of Mil-C-5015. They provide secure and environmentally sealed connections, ensuring signal integrity and power delivery in challenging conditions where resistance to vibration, shock, moisture, and temperature extremes is critical, while often emphasizing intermateability with other major brands for flexibility and broad compatibility.
