Product Code:SAE AS81582
Title:Connectors, Electrical, Bayonet Coupling, Environment Resisting, Umbilical, General Specification For
Issuing Committee:Ae-8c1 Connectors Committee
Scope: This specification covers environment-resisting, quick disconnect, EMI/RFI shielded and non-shielded umbilical, electric connectors and adapter assemblies with removable crimp or nonremovable solder-type contacts and accessories. Connectors are rated for operation from -55 °C (-67 °F) to 200 °C (392 °F). Adapter assemblies are rated for operation from -55 °C (-67 °F) to 125 °C (257 °F). The upper temperature is the maximum internal hot spot temperature resulting from any combination of electrical load and ambient temperature.
Rationale: This specification covers environment-resisting, quick disconnect, EMI/RFI shielded and non-shielded umbilical, electric connectors and adapter assemblies with removable crimp or nonremovable solder-type contacts and accessories. Connectors are rated for operation from -55 °C (-67 °F) to 200 °C (392 °F). Adapter assemblies are rated for operation from -55 °C (-67 °F) to 125 °C (257 °F).
