Browse Topic: Connectors and terminals
This specification covers a standard acrylonitrile butadiene (NBR-H) rubber stock with medium-high acrylonitrile content in the form of molded test slabs.
This specification covers four series of electrical connectors (plugs and receptacles) with removable crimp contacts and accessories (see 6.1). AS81511 connectors are not recommended for new design. All AS81511 detail sheets that specified class D and/or H have been cancelled without replacement, therefore all class D and H requirements have been deleted from this specification. Electrical, mechanical and environmental features of these connectors include: Environment resisting at sea level and high altitude. Quick disconnect. RFI/EMI (Radio Frequency Interference/Electromagnetic Interference) protection (includes shell to shell grounding spring members). High density insert arrangements. Low level circuit capabilities. Scoop-proof. Fluid resistant class provided. High temperature class provided. Several voltage service ratings available. Individual contact release from the rear of the connector (series 3 and 4 only).
This specification covers crimp-style aluminum lug terminals and conductor splices for aluminum aircraft wire. Lug terminals and conductor splices are hereafter called “terminals.”
SCOPE IS UNAVAILABLE.
This SAE Aerospace Standard (AS) covers miniature, composite, high density, threaded coupling, self-locking, circular, environment-resistant, electrical connectors utilizing removable crimp contacts, and associated hardware, which are capable of continuous operation within a temperature range of -65 to +175 °C (-85 to 347 °F). These connectors are supplied under an AS9100 reliability assurance program. See 6.1 for intended use and applications.
NASA's Space Communications and Navigation (SCaN) Program and the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, have successfully tested wideband technology that allows spacecraft to communicate with both government and commercial networks for the first time. Launched July 23, 2025, aboard a SpaceX Falcon 9 rideshare mission, the Polylingual Experimental Terminal (PExT) is demonstrating multilingual wideband terminal technology. Hosted on a satellite from York Space Systems, PExT enhances a spacecraft's communications subsystem, enabling mission controllers to track and exchange data more efficiently across a broad range of networks and frequencies.
