Product details
The 7-1437657-3 by TE Connectivity AMP Connectors revolutionizes Terminal Blocks - Barrier Blocks technology, crafted for aerospace-grade electrical systems requiring uncompromising reliability. This terminal block excels in avionics and satellite applications where weight savings and vibration resistance are critical. Its space-qualified materials maintain stable contact resistance across extreme temperature fluctuations and vacuum conditions.Engineered as a Barrier Block, this component provides hermetic sealing against outgassing in low-pressure environments.The 3 isolated circuits support redundant system architectures essential for flight-critical applications.With 3 military-spec entry points, it accommodates shielded cabling for EMI-sensitive installations.The 0.438" (11.12mm) aerospace-grade pitch maintains arc resistance while minimizing mass in payload-sensitive designs.Its 1 row configuration optimizes weight distribution without sacrificing current density.Rated for 30A in thin-atmosphere conditions, it exceeds MIL-STD-704 power quality requirements.The 600V dielectric strength ensures operation in partial discharge-prone environments.Compatible with 10-18 AWG aerospace wire standards, including fluoropolymer-insulated variants.The Screws with Captive Plate system maintains constant contact pressure in high-G force scenarios.Featuring PC Pin interface, it enables vibration-proof PCB mounting for modular avionics.The 3 Wall (Tri) design prevents corona discharge at high altitudes.Incorporating Flange, it meets DO-160 standards for environmental testing in aerospace electronics.Black housing incorporates radar-absorbent properties for stealth applications.
