This type of connector is designed with a circular interface and housing to quickly and easily connect and disconnect signal, power, and optical circuits. Circular connectors are often preferred in military, aerospace, and industrial applications: these can be connected and disconnected without the use of coupling tools such as torque wrenches. TE’s circular connectors offer rugged solutions that have been engineered for reliable performance in a wide variety of harsh environment applications.


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.
