253-104

The 253-104 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 2 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.0.197" (5.00mm) spacing prevents corona discharge at 30,000 feet. The graded insulation design manages partial discharge inception voltage at altitude.Vertical 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 8 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 16-20 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 - Leg Spring, Push-In Spring process meets NASA-STD-8739.4 for space applications. Self-fluxing contacts eliminate the need for cleaning in oxygen-rich environments.The Gray coding follows MIL-STD-1472 human factors standards. Luminescent markings remain visible in cockpit blackout conditions.
