CONNECTORS, ELECTRICAL, RECTANGULAR, NANOMINIATURE, POLARIZED SHELL, GENERAL SPECIFICATION FOR
|Publication Date:||3 August 2017|
This specification covers the detail requirements for nanominiature connectors terminated on printed circuit boards or attached to cable assemblies. The connector contacts are densely packed with .025 (0.64 mm) inch spacing between contact centers in the same row. These connectors are intended for use in assemblies requiring very densely packaged electronic components, and are commonly used in digital applications.
These connectors are intended for use for interconnections on printed wiring board, printed wiring board to cable, cable to panel, or cable to cable on miniaturized equipment sub-assemblies with... View More
These connectors are intended for use for interconnections on printed wiring board, printed wiring board to cable, cable to panel, or cable to cable on miniaturized equipment sub-assemblies with low power requirements. The connectors covered by this specification are militarily unique because of requirements to operate satisfactorily under sinusoidal vibrations of 10 to 2000 Hz at up to 20 g's; withstand 48 hours of salt spray without exposure of base metals which will affect performance, or cause pitting or porosity of the finish; withstand 100 g's of shock with no electrical discontinuity; and operate at temperatures of minus 55 to plus 125 degrees Celsius. Commercial electronic components are not designed to withstand these extreme conditions or sudden environmental changes, and would experience catastrophic failure.View Less
