Eaton 85100A1418SY50 MIL-DTL-26482 Receptacle - SI
Part Number: 85100A1418SY50
Quick Summary
Eaton 85100A1418SY50 is a square flange MIL-DTL-26482 receptacle designed for rugged aerospace and industrial harness connections. Engineers often struggle to maintain sealed, vibration-resistant connections in extreme environments; this receptacle’s cadmium-plated aluminium shell and solder-cup contacts deliver improved durability and low contact resistance. It carries MIL-DTL-26482 SI qualification and REACH compliance, supporting safety and regulatory requirements. The 85100A1418SY50 integrates an 18-position contact layout within a compact 41 mm length and 28.9 mm footprint, making it suitable for space-constrained harnesses. The straight backshell, adaptor configuration, and 1/3 bayonet coupling simplify installation and mating, while the “delivered with connector” option reduces assembly steps and testing time.
