Browse Circular Connector Products

A circular connector is a cylindrical, multi-pin electrical connector that contains contacts that power electrical devices, transmit data, or transmit electrical signals. A circular connector is designed to withstand harsh environments and reliably deliver data. It is designed with a circular interface and housing to quickly and easily connect and disconnect signal, power, and optical circuits without the use of coupling tools such as torque wrenches. The contacts are typically surrounded by a composite or metal shell and are embedded in insulating material to maintain their alignment. The contacts are usually paired with a cable, making them especially resistant to accidental decoupling or environmental interference. TE’s circular connectors offer rugged solutions that have been engineered for reliable performance in a wide variety of harsh environmental applications, including aerospace, broadcast, defense and security, electronics, energy, industrial, instrumentation, medical, and transportation.

CIRCULAR CONNECTORS AND CONNECTOR CONTACTS

In avionics, our rugged MIL-SPEC circular connectors and components can reliably deliver data up to 10 Gb/s, through time tested connector platforms that will help withstand extreme vibration and temperatures. In airline infotainment systems, circular connectors are used to link electrical and optical circuits with lightweight, space-saving designs. In aircraft landing gear and engines, specialized circular connectors offer a high-reliability connection sealed against moisture and chemicals. In industrial machinery, circular connectors provide robust housings and strain relief to help withstand impact, shock and vibration, to help prevent damage to connection points. From aircraft to offshore drilling platforms to the factory floor, TE Connectivity can help provide circular interconnect solutions that are engineered for your needs.
