721-604/019-042

WAGO Corporation's 721-604/019-042 represents a breakthrough in Terminal Blocks - Headers, Plugs and Sockets technology for mission-critical applications. Designed for aerospace and defense systems, this interconnect solution combines military-grade reliability with cutting-edge signal transmission capabilities. The Terminal Blocks - Headers, Plugs and Sockets delivers uncompromising performance in radar and avionics applications.The Plug, Male Pins architecture incorporates EMI/RFI shielding for sensitive electronic environments. Compared to commercial-grade alternatives, it provides 40dB better noise suppression at GHz frequencies.Configurable in 4 positions, the modular system supports redundant power architectures. The parallel contact arrangement ensures current sharing balance within 5% variance.4 positions per level optimize signal path lengths for time-critical applications. The symmetrical layout minimizes propagation delay differences between channels.With 1 level options, designers can implement compact vertical stacking. This approach reduces signal path inductance by 25% compared to traditional horizontal layouts.The 0.197" (5.00mm) pitch configuration meets aerospace wire separation standards. The optimized spacing prevents corona discharge at high altitudes while maintaining signal integrity.Engineered with 180° entry options, the strain relief system withstands 50G shock loads. The military-spec compliant design prevents wire pull-out during vibration events.The Screwless - Push-In Spring technology ensures gas-tight connections for oxygen-rich environments. Special material formulations prevent fretting corrosion in high-vibration scenarios.Free Hanging (In-Line) installation satisfies DO-160G requirements for airborne equipment. The captive hardware design prevents loose fasteners in critical flight systems.Meeting 12A IEC standards for naval applications, the design prevents saltwater corrosion. The hermetically sealed versions are rated for submarine deployments.The 630 V certification includes testing for altitude-induced dielectric breakdown. Third-party verification confirms compliance with DEF STAN 59-411 requirements.Certified for 15 A continuous current, the contacts utilize beryllium copper springs. This material maintains elastic properties across the full military temperature range.The 600 V rating includes 200% derating margin for aerospace applications. The insulation system remains stable at 50,000 feet altitude with minimal PDIV degradation.Accepting 12-28 AWG wires, the termination system accommodates both standard and high-flex conductors. The dual-stage strain relief prevents conductor fatigue.The Gray housing meets NATO stock number requirements for quick identification. The high-visibility material includes night-vision compatible markings.Performance guaranteed across -60°C ~ 100°C range, exceeding MIL-STD-810H specifications. Materials testing confirms no outgassing in vacuum environments.Tin surface treatment provides 10,000 mating cycles with minimal wear. The proprietary plating process achieves 50% higher hardness than industry standards.Incorporating Mounting Flange, the design addresses electromagnetic pulse (EMP) protection requirements. These include Faraday cage construction and transient voltage suppression.
