The 85100E2232PX50 delivers a dense 32-contact square flange receptacle in a compact interface, using solder cup contacts for robust wire terminations. The 32-position layout reduces harness complexity and enables higher channel density in control cabinets and avionics racks, improving signal integrity and reducing panel space. The combination of cadmium plating and an aluminium shell size 22 provides corrosion resistance without excessive weight, supporting long service life in demanding environments. With a 1/3 bayonet coupling, mating is quick and repeatable, minimizing downtime during installation and field servicing. The orientation X and backnut backshell design simplify alignment and secure mounting, helping maintain reliable connections in vibration-prone equipment such as CNC controllers and aerospace actuators. The device ships as a ready-to-use connector, delivered with the connector, enabling faster integration with existing harnesses. Operating temperature range from -40 °C to 125 °C ensures stable performance across cold starts and hot operation, reducing risk of intermittent contacts due to thermal stress. Cadmium plating offers durable contact protection, while REACH compliance aligns with modern regulatory expectations, helping customers maintain environmental responsibility. The product supports multi-contact power and signal paths in one rugged assembly, reducing total cost of ownership by simplifying inventory and maintenance.

FAQs
For installation, prepare a clean panel with the correct square flange cutout and insert the receptacle such that the connector orientation is X. Tighten the backnut securely to ensure the backshell seats properly. The 1/3 bayonet coupling allows quick mating, but verify proper bayonet alignment to avoid damaging the solder cup contacts. Ensure the cadmium plating is handled per regulatory guidelines.
It is designed to withstand -40 °C to 125 °C, preserving contact integrity through temperature swings. The aluminium shell provides structural rigidity, while cadmium plating enhances corrosion resistance. To maximize longevity, perform mating with proper alignment and mature torque control on the backnut to maintain a robust, vibration-resistant connection.
Yes. The MIL-DTL-26482 SI qualification, square flange receptacle format, backnut, and 32-contact layout make it appropriate for aerospace, defense, and high-density industrial automation. Its vibration resistance, lightweight aluminium shell, and compact 34.5 mm by 40 mm footprint support reliable, space-efficient interconnects in demanding environments.
Key compliance points include MIL-DTL-26482 SI qualification for rugged interconnect performance and REACH compliance for environmental regulations. Cadmium plating provides corrosion protection but may require special handling per regional environmental rules. Confirm your project’s certification requirements align with MIL-DTL-26482 and REACH when sourcing this receptacle.
The backnut-backed square flange design enables quick, repeatable mating with low maintenance needs, reducing assembly time and field downtime. The high-density 32-contact layout minimizes harness complexity, while the corrosion-protected cadmium finish extends service life in harsh environments. Overall, you gain lower total cost of ownership through faster servicing and fewer replacement parts in aerospace and industrial automation programs.
