FAQs
The 85100E1811SY50 uses a square flange receptacle with a backnut and straight backshell, delivering secure mounting and straightforward panel installation. It features a Y orientation and 1/3 Bayonet coupling for rapid mating while maintaining vibration resistance. Plan for a compatible panel cutout size and ensure the mating connector aligns with the Y orientation for proper fit and serviceability.
This receptacle supports 11 solder cup contacts in an 11-circuit layout and is configured as a socket (female). With cadmium plating on an aluminium shell and a straight backshell, it provides reliable signal integrity across a wide temperature range (-40 °C to 125 °C). The 1/3 Bayonet coupling ensures secure engagement in demanding environments.
Yes. The MIL-DTL-26482 SI qualification indicates suitability for high-reliability applications, and the operating range (-40 °C to 125 °C) covers extreme aerospace and industrial conditions. The aluminium shell and cadmium plating enhance durability against corrosion and wear, making it well-suited for rugged equipment, avionics, and robust automation systems.
The product is MIL-DTL-26482 SI qualified and REACH compliant, with cadmium plating on an aluminium shell. These certifications support performance in demanding environments and regulatory compliance for European and international applications, while the REACH listing addresses environmental responsibility in materials and processes.
The backnut, 1/3 Bayonet coupling and robust metal shell contribute to secure, vibration-resistant mating, reducing contact wear and loosening over time. Cadmium plating and aluminium construction minimize corrosion under harsh conditions, lowering maintenance needs and downtime. The connector’s ready-to-install configuration accelerates assembly and can shorten commissioning, delivering tangible ROI in fielded systems.
