FAQs
To install the 85100E107SW50, align the receptacle with the panel cutout, insert the backnut from the exterior, and hand-tighten before final torque per your assembly standards. The unit uses a straight backshell and a 1/3 bayonet coupling for quick mating. Ensure the orientation is set to W and confirm contact seating for the solder cup sockets.
The connector provides seven solder cup contacts within a socket (female) arrangement, laid out in a 7-position configuration. Contacts are cadmium plated and supported by an aluminium shell (size 10). Mating employs a 1/3 bayonet coupling with the backnut securing the panel, suitable for a wide operating temperature range from -40 °C to 125 °C.
This receptacle is MIL-DTL-26482 SI qualified, ensuring stringent military interface standards. It also lists REACH compliance for environmental safety. These certifications support aerospace, defense, and industrial automation applications requiring reliable performance and regulatory alignment across global supply chains.
The 85100E107SW50 is well suited for aerospace, defense, and industrial automation environments that demand robust EMI/RFI performance, vibration resistance, and corrosion protection. Its square flange, backnut mounting, and 7-contact solder cup configuration make it a reliable choice for avionics harnesses, rugged control panels, and field-deployed equipment.
Maintenance considerations include inspecting the cadmium-plated shell for corrosion, ensuring the backnut remains securely torqued, and replacing solder cups if solder fatigue is observed. Its durable aluminium shell and SI qualification support long service life, reducing replacement frequency and downtime, which translates to lower total cost of ownership in mission-critical systems.
