1546074-4

The 1546074-4 by TE Connectivity AMP Connectors 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 4 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.0.200" (5.08mm) spacing prevents corona discharge at 30,000 feet. The graded insulation design manages partial discharge inception voltage at altitude.35° (145°) Angle 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.Capable of sustaining 17.5 A under vibration, the contacts use shape-memory alloys to maintain constant pressure. This design prevents fretting corrosion during extended mission profiles.The 300 V isolation rating exceeds MIL-STD-704F aircraft power requirements. Arc-quenching materials prevent plasma formation at reduced atmospheric pressures.Accepting 12-30 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 Screw - Rising Cage Clamp process meets NASA-STD-8739.4 for space applications. Self-fluxing contacts eliminate the need for cleaning in oxygen-rich environments.Interlocking (Side) include built-in transient voltage suppression. The nanocrystalline coating provides atomic oxygen protection for low Earth orbit applications.The Black coding follows MIL-STD-1472 human factors standards. Luminescent markings remain visible in cockpit blackout conditions.
