40990-4

The 40990-4 from TE Connectivity AMP Connectors revolutionizes Terminals - Specialized Connectors for aerospace power distribution systems. Its lightweight construction reduces payload weight while meeting DO-160G standards for extreme environmental performance.With Weld Tab construction, the terminal achieves 2000+ mating cycles at 50G vibration levels. The beryllium copper contacts maintain stable contact force across -65 C to 200 C operational ranges.The Crimp process creates cryogenically stable joints that withstand thermal cycling from -200 C to +300 C. NASA-approved encapsulants prevent outgassing in vacuum environments.Certified for 16-20 AWG aerospace wiring, the terminal's current rating exceeds MIL-W-22759/34 specifications. The patented crimp profile ensures uniform compression across all conductor strands.
