Feature is the 19 solder cup contacts enable 19 discrete signal paths in a compact footprint, reducing wiring complexity and panel cutouts. Business impact is lower wiring costs, simpler inventory, and faster assembly on crowded control panels in industrial machinery and automation systems. Application includes I/O modules, sensors, and control units where space is at a premium. Feature a 1/3 bayonet coupling offers fast mating with proven vibration resistance; business impact is reduced installation time and lower risk of misalignment, benefiting field service teams and assembly lines. Application in harsh environments such as aerospace and heavy equipment improves reliability during maintenance windows. Feature a backnut backshell enhances sealing and EMI performance, reducing dust ingress and electrical noise; business impact is longer component life and safer operation in dusty, humid, or salt-laden atmospheres. Application spans outdoor automation, material handling, and defense-related machinery. Feature aluminium shell provides strength with light weight, aiding panel design and energy efficiency; business impact is easier handling during assembly and lower overall weight in equipment. Application includes rugged industrial enclosures and mobile machinery. Feature cadmium plating adds corrosion protection; business impact is extended service life in harsh environments, supporting longer replacement cycles. Application for marine, outdoor, and industrial sectors with salt spray exposure. Feature operating temperature range from -40 °C to 125 °C ensures performance across cold starts and hot operation; business impact is reduced risk of thermal-related failures and wider serviceability. Application across automotive, aerospace, and process industries. Feature square flange receptacle with backnut geometry improves mechanical compatibility and panel sealing; business impact is simpler retrofit and faster OEM integration. Application in legacy systems requiring reliable multi-pin connections. Feature orientation Y and delivered with connector simplify harness routing and installation planning; business impact is faster wiring, fewer assembly errors, and improved traceability in complex assemblies. Application in high-density control cabinets and modular systems.

FAQs
Install as a square flange receptacle with a backnut backing. Ensure panel cutout matches a size compatible with shell size 14 and align with orientation Y. Use the 1/3 bayonet coupling for quick mating, and wire using the solder cup contacts. Verify cadmium plating compatibility with your environmental protection requirements.
The connector provides 19 solder cup contacts in an aluminium shell size 14 with a backnut backshell. It supports a -40 °C to 125 °C operating range, cadmium plating, and a 1/3 bayonet coupling in a square flange receptacle configuration. Overall dimensions are 32.7 mm length, 28.9 mm width, and 28.9 mm height, with a weight around 21.5 g.
Yes. The 85100E1419SY50 is MIL-DTL-26482 SI qualified, designed for stringent aerospace and defense environments. It also carries REACH compliance, supporting regulatory expectations in international supply chains while delivering reliable mating, vibration resistance, and EMI performance in mission-critical equipment.
Key certifications include MIL-DTL-26482 SI qualification and REACH compliance. The cadmium-plated finish provides corrosion protection in harsh environments, while the aluminium shell offers mechanical robustness. These attributes support long service life and regulatory alignment in regulated sectors such as aerospace and industrial automation.
ROI benefits come from reduced wiring complexity (19 contacts in one receptacle), faster installation via 1/3 bayonet coupling, and longer service life due to corrosion protection and a wide temperature range. Additionally, the delivered-with-connector option simplifies inventory and maintenance planning, lowering downtime and accelerating panel upgrades.
