Product details
Weidmüller's 1876990000 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 Header, Male Pins, Shrouded (4 Side) 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 2 positions, the modular system supports redundant power architectures. The parallel contact arrangement ensures current sharing balance within 5% variance.2 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 0.200" (5.08mm) pitch configuration meets aerospace wire separation standards. The optimized spacing prevents corona discharge at high altitudes while maintaining signal integrity.The 90°, Right Angle, Under Board options facilitate conformal packaging in airborne systems. The under-board variants enable low-profile installations in wing-mounted equipment.The Solder technology ensures gas-tight connections for oxygen-rich environments. Special material formulations prevent fretting corrosion in high-vibration scenarios.Through Hole installation satisfies DO-160G requirements for airborne equipment. The captive hardware design prevents loose fasteners in critical flight systems.Meeting 27.5A IEC standards for naval applications, the design prevents saltwater corrosion. The hermetically sealed versions are rated for submarine deployments.The 400 V certification includes testing for altitude-induced dielectric breakdown. Third-party verification confirms compliance with DEF STAN 59-411 requirements.Certified for 18.5 A continuous current, the contacts utilize beryllium copper springs. This material maintains elastic properties across the full military temperature range.The 300 V rating includes 200% derating margin for aerospace applications. The insulation system remains stable at 50,000 feet altitude with minimal PDIV degradation.The Black housing meets NATO stock number requirements for quick identification. The high-visibility material includes night-vision compatible markings.Performance guaranteed across -50°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 Mating Flange, Solder Retention, the design addresses electromagnetic pulse (EMP) protection requirements. These include Faraday cage construction and transient voltage suppression.
