High-density contact array delivers more connections in a compact footprint, reducing panel real estate while enabling high-throughput assemblies. This translates to lower harness complexity and faster install times, boosting overall equipment efficiency in aerospace and heavy industrial environments. The 27-contact layout supports robust signal and power distribution for demanding controls, improving reliability in vibration-prone applications. Cadmium plating provides corrosion resistance in harsh environments, extending service life and reducing maintenance costs for fielded platforms. The aluminium shell reduces weight without compromising strength, contributing to improved fuel efficiency in airborne systems and easier handling during assembly. The 1/3 bayonet coupling offers quick mating and secure retention, minimizing downtime during field service and re-mating scenarios. Delivered with connector options and W orientation simplify installation planning and streamline replacement cycles, especially in retrofit projects. Operating from -40 °C to 125 °C, this receptacle maintains performance across extreme temperature swings common in aerospace and industrial plants, supporting uptime and regulatory compliance.

FAQs
The 85100A2027PW50 uses a square flange receptacle with a 1/3 Bayonet coupling (Bayonet) and a straight backshell. It ships with connector options already included and supports W orientation for solder cup contacts. This configuration minimizes additional components and simplifies installation, while ensuring secure, vibration-resistant mating in aerospace and industrial equipment.
Operating temperature ranges from -40 °C to 125 °C, which supports use in extreme environments. The shell is aluminium to reduce weight, with cadmium plating for corrosion resistance. It features 27 solder cup contacts in a square flange receptacle, aiding high-density circuit layouts. The backshell angle is straight, and overall footprint remains compact for tight panels and enclosures.
Yes. It is MIL-DTL-26482 SI qualified, designed for aerospace and defense interconnects. The square flange receptacle, 27-contact configuration, and rugged materials support high-reliability assembly in aircraft, spacecraft, and mission-critical equipment where vibration, temperature, and EMI considerations are paramount.
The product is REACH compliant, aligning with regulatory expectations for materials used in European and global markets. While cadmium plating offers robust corrosion resistance, procurement should verify regional cadmium-use requirements. Always confirm with your compliance team and the supply chain to ensure alignment with local environmental standards and aerospace program requirements.
Delivered with connector options and a straight backshell, the 85100A2027PW50 reduces step-count during assembly and minimizes field re-work. The 27-contact arrangement supports a single, dense harness, cutting harness routing time and panel penetrations. Combined with its wide operating temperature range and robust materials, it lowers maintenance costs and extends service life, yielding tangible ROI over platform lifecycles.
