FAQs
Yes. The 85100E1626S50 is designed as a square flange receptacle with backnut mounting and a 1/3 Bayonet coupling, compatible with Eaton Souriau 851-series mating connectors. Ensure the connector orientation is set to N and that the solder cup contacts are correctly terminated to the harness. This reduces mating stress and ensures reliable field serviceability.
The product provides 26 solder cup contacts in a 26-position cavity layout, suitable for dense interconnections in compact assemblies. The contacts are socket (female) and delivered loaded, with cadmium plating on an aluminum shell. While current rating is not specified, the design supports robust, vibration-resistant terminations in temperature ranges from -40 °C to 125 °C.
Yes. The connector is specified for a wide operating temperature range from -40 °C to 125 °C, enabling dependable performance in extreme industrial and aerospace environments. The aluminum shell with cadmium plating adds corrosion resistance, while the MIL-DTL-26482 SI qualification confirms suitability for demanding applications.
Cadmium plating provides enhanced corrosion resistance for aluminum shells, which helps extend service life in challenging environments. However, users should account for regulatory considerations regarding cadmium-containing parts; ensure compatibility with your RoHS/REACH requirements and facility handling procedures while evaluating long-term maintenance and disposal.
Using a high-density 26-pin receptacle with a backnut and quick 1/3 bayonet mating reduces install time, maintenance windows, and hardware inventory needs. The robust environmental tolerance minimizes downtimes in harsh factories or outdoor installations, delivering accelerated ROI through fewer service calls, improved uptime, and easier spare-part procurement for legacy and upgrade projects.
