Product details
Weidmüller's 1278230000 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 4 positions, the modular design supports redundant network architectures. The dual-path contact arrangement ensures signal continuity during vibration events.2 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.
