FAQs
MIL-DTL-26482 SI qualification confirms conformance to a widely used military interface standard, ensuring robust electrical performance under vibrational loads, environmental extremes, and repeated mating cycles. For the 85100E1412SX50, this translates to dependable signal integrity and power transmission in aerospace and defense deployments, with consistent interchangeability across compatible 851 series receptacles.
Begin by aligning the square flange with the mounting surface and inserting the backnut from the exterior side. Secure the backnut to achieve proper panel sealing, then mate the 12 solder cup contacts with the corresponding plug or harness. Ensure the straight backshell orientation (X) is maintained to preserve alignment and ease future disassembly.
Yes. The 85100E1412SX50 combines MIL-DTL-26482 SI qualification, 1/3 bayonet coupling, and a cadmium-plated aluminium shell to resist vibration and corrosion. Its 12-contact layout supports robust power and signal distribution, while the backnut and straight backshell configuration simplifies secure mounting in enclosures subject to dynamic loads.
The connector is MIL-DTL-26482 SI qualified and REACH compliant, addressing critical aerospace and defense regulatory requirements. The cadmium plating provides corrosion protection, though buyers should evaluate RoHS considerations for their specific program. The product is designed for operation across -40 to 125 °C, supporting wide environmental demands.
The 85100E1412SX50 delivers long-term uptime through MIL-grade reliability, fast field mating, and reduced maintenance due to corrosion resistance and broad temperature tolerance. Its compact footprint and straightforward panel installation lower initial installation costs, while standardized 12-pin configuration eases spares management and future scalability, contributing to lower total cost of ownership.
