FAQs
The 85100A1418S50 supports a straight backshell with an adaptor backshell option and is delivered with a connector. It features a square flange receptacle design, 18 solder cup contacts, and a 41 mm length, enabling straightforward panel mounting and rapid replacement in constrained enclosures. Orientation is N, which simplifies harness routing in compact layouts.
MIL-DTL-26482 SI qualification provides verified performance under vibration, thermal cycling, and other harsh conditions typical of aerospace environments. Combined with a 18-contact solder cup arrangement, cadmium plating for corrosion resistance, and an aluminium shell, the connector supports reliable long-term operation from -40 °C to 125 °C, aiding regulatory audits and mission-critical reliability.
Yes. With 18 contacts in a compact 41 mm length square flange form factor and a 1/3 bayonet coupling, the 85100A1418S50 provides high-density I/O in tight panel spaces. This enables richer signaling in avionics, control panels, and defense equipment without compromising clearance or assembly neatness, improving overall system reliability and simplify harness routing.
This receptacle is MIL-DTL-26482 SI qualified, offering traceable performance data essential for airborne and defense programs. It also lists REACH as an environmental condition, supporting regulatory compliance for chemical restrictions. When sourcing, verify the supplier’s documentation for qualification approvals, lot-level traceability, and applicable program-specific compliance requirements.
Cadmium plating delivers long-term corrosion resistance, which reduces maintenance cycles in corrosive environments. Lifecycle considerations include periodic inspection of solder cups for tin whisker growth and ensuring mating surfaces remain clean to preserve low-contact resistance. The aluminium shell provides a favorable weight-to-strength ratio, contributing to lower cumulative maintenance costs in aerospace and industrial platforms.
