Product details
Keystone Electronics's 8722 revolutionizes Terminal Blocks - Headers, Plugs and Sockets technology for space-grade applications. This radiation-hardened interconnect solution meets the extreme demands of satellite and launch vehicle systems while maintaining signal integrity in the space environment. The Terminal Blocks - Headers, Plugs and Sockets delivers reliable performance from LEO to deep space missions.The Plug for Unshrouded Header architecture incorporates radiation shielding for space electronics. Compared to commercial components, it provides 100x better TID (Total Ionizing Dose) resistance up to 1Mrad(Si).Configurable in 2 positions, the modular system supports redundant spacecraft bus architectures. The cross-strapped contact arrangement ensures single-fault tolerance.2 positions per level optimize mass efficiency in satellite designs. The lightweight construction reduces launch payload while maintaining reliability.With 1 level options, designers can implement compact stacking in CubeSat applications. The modular approach allows configuration from 1U to 12U form factors.The 0.138" (3.50mm) pitch configuration prevents vacuum arc formation in LEO environments. The specially shaped contacts inhibit electron emission in plasma conditions.Engineered with 90° entry options, the strain relief system survives 50G launch vibrations. The zero-outgassing materials meet NASA ASTM E595 requirements.The Screw - Leaf Spring, Wire Guard technology ensures reliable connections in zero-gravity conditions. The kinematic design prevents contact separation during thermal cycling in orbit.Free Hanging (In-Line) installation satisfies MIL-STD-1540 requirements for launch vehicles. The pyroshock-resistant design maintains integrity during stage separation events.Certified for 6 A in vacuum, the contacts utilize special alloys to prevent cold welding. The dry-lubricated surfaces maintain performance across -150 C to 150 C orbital cycles.The 250 V rating includes design margin for solar array stringing. The insulation system resists Paschen breakdown in low-pressure environments.Accepting 16-22 AWG space-grade wires, the termination handles both coaxial and twisted pairs. The Kapton-insulated variants are rated for extravehicular use.The Blue housing uses optically stable pigments for thermal control. The specially formulated surface maintains consistent / ratio throughout the mission.Performance guaranteed across -30°C ~ 120°C range, from eclipse cooling to direct solar exposure. Materials testing confirms operation in GEO 15-year mission profiles.Tin surface treatment provides 500 mating cycles in vacuum. The gold-over-nickel plating prevents atomic oxygen erosion in LEO.Incorporating Interlocking (Side), the design addresses single-event effects (SEE) mitigation. These include radiation-hardened dielectrics and latch-up resistant geometries.
