3、GH DENSITY, QUICK DISCONNECT, ENVIRONMENT RESISTING; AND ACCESSORIES GENERAL SPECIFICATION FOR This specification is approved for use by Naval Air Systems Command, Department of the Navy, and is available for use by all Departments and Agencies of the Department of Defense. The MIL-C-81511 connector
4、s have been declared INACTIVE FOR NEW DESIGN after 30 April 1975 by decision of the Department of Defense. This does not preclude their use for maintenance, repair, or resupply purposes, nor does it preclude use in design circumstances wherein the connectors must interface with the connectors being
5、supplied with Government Furnished Equipment. 1. SCOPE 1.1 Scqpe. This specification covers four series of electrical connectors (plugs and receptacles) with removable crimp and nonremovable solder contacts and accessories (see 6.1). Electrical, mechanical and environmental features of these connect
6、ors include: a. Environment resisting at sea level and high altitude b. Quick disconnect. c. RFIIEMI (Radio Frequency Interference/Electromagnetic Interference) protection (includes shell to shell grounding spring members). d. High density insert arrangements e.
