FAQs
The 85100E1626SY50 is a square flange receptacle with a backnut and straight backshell designed for use with 851-series systems. Its 26-contact layout and 1/3 bayonet coupling align with standard 851-series accessories, simplifying retrofit or upgrade projects and ensuring consistent mechanical and electrical mating in aerospace and industrial installations.
MIL-DTL-26482 SI qualification indicates a proven level of performance under demanding conditions, including vibration, environmental exposure, and electrical contact integrity. For buyers, this means the connector is suitable for mission-critical equipment in aerospace, defense, and high-reliability industrial applications, with reduced risk of field failures.
Yes. With 26 solder cup contacts in a compact 16-shell size and a 26-position layout, the 85100E1626SY50 supports high-density harnessing. The square flange receptacle, backnut, and 1/3 bayonet coupling facilitate secure mounting and reliable, repeatable mating, aiding clean harness routing in control cabinets and equipment racks.
The connector operates from -40 °C to 125 °C, enabling reliability across extreme climates. Cadmium plating and an aluminum shell confer corrosion resistance, while REACH compliance addresses environmental safety concerns. When selecting for outdoor or humid environments, this combination helps ensure long-term performance and reduced maintenance.
The 85100E1626SY50’s robust mechanical design, corrosion-resistant cadmium finish, and MIL-DTL-26482 SI qualification contribute to lower maintenance and replacement rates. The secure backnut and 1/3 bayonet coupling reduce wear from mating cycles, while high-shell durability supports longer service intervals in harsh environments, improving total cost of ownership over time.
