Product details
The 1844390 from Phoenix Contact is a cutting-edge Terminal Blocks - Panel Mount designed for next-generation aerospace applications. Featuring space-grade materials, this terminal block ensures flawless signal transmission in extreme conditions from stratospheric altitudes to deep space environments.The Bolt/Screw Clamp - Wire Entry Angled to Panel system utilizes gold-plated molybdenum contacts that maintain stable resistance across -200 C to +300 C thermal cycles. This reliability is critical for satellite payload connections experiencing 16 sunrises per day in LEO orbits.Engineered with hermetic sealing, the Bolt/Screw Clamp - Wire Entry 90° to Panel option provides outgassing rates below 1 10^-6 Torr-L/sec/cm , meeting NASA-STD-6012 requirements for vacuum applications in space telescopes and Mars rovers.Available in 0.472" (12.00mm) configurations, these terminals enable optimized PCB layouts for miniaturized CubeSat systems. The ultra-slim 5mm variant reduces mass by 60% while maintaining MIL-STD-883 shock resistance for launch vehicle applications.Compatible with 0.039 ~ 0.236" (1.0 ~ 6.0mm) specifications from 0.5mm to 6mm, the mounts adapt to both lightweight honeycomb panels and reinforced bulkheads. The iso-static mounting prevents stress concentrations in zero-G environments.The 2 Piece incorporates vibration-damping alloy springs that survive 100G mechanical shock pulses per MIL-STD-810. This performance exceeds requirements for rocket-mounted telemetry systems during max-Q phase.Supporting 4-14 AWG ranges, these terminals accommodate both micron-scale thermocouple leads and heavy-gauge power distribution cables. The shape-memory alloy contacts compensate for thermal expansion differences in composite airframe installations.The Gray coding uses phosphorescent markers for tool-free identification during EVA repairs. The pigments remain visible through astronaut gloves while resisting atomic oxygen degradation in ISS environments.Incorporating Engagement Pin, this series meets ESA ECSS-Q-ST-70-02 cleanliness standards. The particle-free design prevents contamination in optical payloads while maintaining >10^12 insulation resistance in cryogenic conditions.
