Space-Grade MIL-DTL-38999 Type Circular Blind-Mate Connectors

Space-Grade Circular Blind-Mate Connectors IAW MIL-DTL-38999 for use in Interconnection and Separation of Instrumentation Panels, Satellites, Scientific Research Payloads, and other Release Applications

Series 253

Glenair Series 253 blindmate connectors are designed to meet applicable environmental, electrical and mechanical performance characteristics of D38999 Series III. The technology is well suited for use in commercial rackand-panel instrumentation applications, as well as a blind-mate solution for satellite deployment, scientific research and development payloads, interstage, UAV, and munitions release and more.

• Adjustable separation force (AKA assisted-release, zero extraction force) solutions
• Blind-mate, fixed and float-mount interconnects for non-ITAR commercial as well as military/defense applications
• Misalignment accommodation and special auxiliary sealing for trouble-free blind mating in environmental applications
• Available in most symmetrical D38999 (MIL-STD-1560) insert arrangements with contacts sizes from #23 to #8
• Selected materials offer low outgassing properties and high resistance to both corrosion and stress corrosion cracking
• NASA outgassing bake-out process available
• Designed to withstand the rigors of launch and flight — including shock, vibration, thermal vacuum, acceleration, and temperature extremes
• Standard accessory threads and teeth per MIL-DTL-38999 accommodate a wide range of backshell accessories
• Crimp-removable contacts standard. Consult factory for PC tails, dual-flange standoffs, custom blind-mate configurations, and hermetically sealed options
