Eaton 85100A1214PW50 Receptacle - MIL-DTL-26482 SI
Part Number: 85100A1214PW50
Quick Summary
Eaton 85100A1214PW50 Receptacle is a MIL-DTL-26482 SI qualified connector for harsh-environment aerospace and rugged industrial wiring. Field failures from moisture ingress and misalignment are costly, and bulky assemblies complicate panel installation. MIL-DTL-26482 SI qualification, REACH compliance, and cadmium plating provide corrosion resistance, while an aluminum shell keeps weight down. With straight backshell adaptor, W orientation, and 14-contact solder‑cup layout, it enables quicker, reliable mating in confined panels. Designed for operation from -40 to 125 °C, it supports aerospace, defense, and automation applications with extended service life. OEMs appreciate the compatibility with 1/3 bayonet coupling and 4 cavities #16, which simplifies harness design.

Feature → 14 contacts and 1/3 bayonet coupling provide a high-contact density with secure mating. This reduces harness complexity and improves vibration resistance, translating to fewer field retimes and less downtime in aircraft and automated lines. Application: aerospace harnesses, military vehicles, and rugged industrial equipment benefit from a single housing that accommodates both control signals and power within a compact footprint. Feature → Cadmium plating on an aluminum shell offers proven corrosion protection in harsh environments. Business Impact: longer service life in salt spray, humidity, and temperature cycling reduces maintenance costs. Application: military, aerospace, and offshore equipment where reliability matters. Feature → Backshell adaptor with straight orientation and W alignment simplifies installation and cable routing. Business Impact: faster assembly, consistent mating alignment, and reduced risk of improper orientation. Application: panel builders, OEMs, and field service teams in automation cabinets and avionics harnesses. Feature → Operating temperature -40 to 125 °C ensures performance across climates. Business Impact: robust operation during thermal cycling and in high-temperature environments, reducing the need for frequent replacements. Application: automotive, industrial automation, and aerospace installations. Feature → Delivered with connector with 14 contacts, 4 cavities #16, and solder cup contacts. Business Impact: plug-and-play readiness, faster field integration, and consistent signal integrity. Application: control cabinets, robotics, and automation panels.

FAQs
Install by aligning the panel holes with the square flange and W-oriented backshell. Use the 1/3 bayonet coupling to mate; rotate to lock until a positive engagement is felt. Ensure correct mating plug is seated and verify contact delivery is loaded before final panel tightening. Use appropriate seals and mounting hardware as required by your enclosure design.
The device features 14 solder‑cup contacts arranged in 4 cavities (#16). It has a straight backshell adaptor with a 14-contact, 1/3 bayonet interface, aluminum shell (shell size 12), cadmium plating, overall length about 41 mm, and a compact 26.5 × 26.5 mm profile. Operating temperature ranges from -40 °C to 125 °C, weight roughly 19.8 g, delivering reliable performance in demanding environments.
Yes. It carries MIL-DTL-26482 SI qualification and is designed for harsh environments typical of aerospace and defense programs. The combination of a cadmium-plated aluminum shell, 1/3 bayonet coupling, and a straight backshell provides robust mating, vibration resistance, and long service life in aviation harnesses and spacecraft installations.
The connector is listed with REACH environmental compliance, reflecting its suitability for regulated markets. Cadmium plating is historically used for corrosion protection in aerospace; ensure your specific procurement region and project requirements align with current cadmium usage policies and any local RoHS constraints.
The W orientation paired with the straight backshell adaptor streamlines cable routing and mating alignment, reducing misorientation risks. This simplifies panel layout, accelerates wiring, and minimizes the chance of incorrect plug orientation during assembly—beneficial for high-volume automation builds and field service operations.
