Product details
The 257-743/999-950 by WAGO Corporation is a cutting-edge Terminal Blocks - Wire to Board solution designed for aerospace and defense applications. This mil-spec terminal block delivers unmatched reliability in extreme conditions, featuring hermetic sealing and radiation-resistant materials. The 510KBA-BAAG variant meets DO-160G standards for airborne equipment, ensuring signal integrity in avionics and satellite systems.With 1 independently shielded tiers, this configuration prevents electromagnetic interference between critical systems. Each level incorporates RFI gaskets that maintain 60dB shielding effectiveness up to 18GHz.The 1 high-reliability contacts feature redundant termination paths. Military-grade crimp technology ensures gas-tight connections that survive 1000+ thermal shock cycles from -65 C to 150 C.Horizontal with Board design enables cable routing in confined aircraft bays. The oblique-angle version reduces harness weight by 15% through optimized wire pathing in airframe structures.Accepting 12-28 AWG MIL-W-22759/16 wires, the termination resists mechanical fatigue. The dual-stage strain relief prevents conductor breakage under 50G shock loads.Through Hole installation complies with AS9100 aerospace standards. Vibration-resistant lockwashers maintain torque integrity despite acoustic loading.The Screwless - Push Button Clamp process meets NASA-STD-8739.4 for space applications. Self-fluxing contacts eliminate the need for cleaning in oxygen-rich environments.Push Button Actuated include built-in transient voltage suppression. The nanocrystalline coating provides atomic oxygen protection for low Earth orbit applications.The Gray coding follows MIL-STD-1472 human factors standards. Luminescent markings remain visible in cockpit blackout conditions.
