Product details
Weidmüller's 1278400000 delivers military-grade Terminal Blocks - Headers, Plugs and Sockets performance for harsh environment computing. Designed for battlefield communication systems, this rugged interconnect solution combines extreme durability with high-speed data transmission capabilities. The Terminal Blocks - Headers, Plugs and Sockets ensures mission-critical connectivity in the most demanding defense applications.The Plug, Female Sockets construction incorporates multi-layer EMI shielding for electronic warfare environments. Compared to commercial equivalents, it provides 70dB better EMP protection up to 10GHz.Configurable in 34 positions, the modular design supports redundant network architectures. The dual-path contact arrangement ensures signal continuity during vibration events.17 positions per level optimize impedance matching for high-speed digital signals. The differential pair arrangement maintains signal integrity at 25Gbps data rates.With 2 level options, designers can implement compact multi-board stacking. This approach reduces signal path length by 40% compared to traditional backplane designs.The 0.138" (3.50mm) pitch configuration meets MIL-STD-1344 requirements for military connectors. The precision spacing prevents arcing in high-altitude low-pressure conditions.Engineered with 180° entry options, the cable retention system withstands 100G shock loads. The positive locking mechanism prevents accidental disconnection during combat maneuvers.The Screwless - Leg Spring, Push-In Spring technology ensures hermetic sealing for submarine applications. The glass-filled polymer housing prevents moisture ingress at 500m depth.Free Hanging (In-Line) installation satisfies MIL-STD-810H requirements for armored vehicles. The vibration-resistant design maintains contact integrity during off-road operations.Meeting 13.4A IEC standards for naval applications, the design prevents galvanic corrosion. The titanium housing is compatible with aluminum and steel hulls.The 320 V certification includes testing for lightning-induced surges. The design withstands 10kV transients per MIL-STD-461G.Certified for 9.5 A surge current, the contacts utilize copper-beryllium alloys. This material maintains spring properties across -55 C to 200 C military range.The 300 V rating includes 300% derating margin for battlefield conditions. The insulation system resists tracking in sand and dust contaminated environments.Accepting 16-26 AWG military-spec wires, the termination handles both shielded and armored cables. The quick-release mechanism enables field repairs under fire.The Black housing meets MIL-STD-3009 requirements for night vision compatibility. The non-reflective surface finish prevents detection in IR spectrum.Performance guaranteed across -50°C ~ 120°C range, exceeding DEF STAN 00-35 requirements. Materials testing confirms operation in Arctic and desert extremes.Tin surface treatment provides 5,000 mating cycles in sandy conditions. The self-cleaning contact design prevents particulate buildup.Incorporating Ejector Latches, the design addresses chemical warfare protection requirements. These include NBC (nuclear, biological, chemical) resistant seals and coatings.
