FAQs
Installation starts with aligning the Z-oriented receptacle to the mating connector, then engaging the 1/3 bayonet coupling until it seats with a defined click. Attach the backnut to secure the housing, ensure proper backshell sealing, and terminate the solder cup contacts according to your cable assignment. Verify mating alignment and torque tolerance on the backnut for reliable performance in vibration-prone environments.
MIL-DTL-26482 SI qualified connectors are designed to meet stringent military and aerospace standards for reliability under shock, vibration, and thermal cycling. For a 32-contact square flange receptacle like 85100E2232PZ50, this provides predictable mating, robust signal integrity, and sealing performance that reduce field failures and maintenance costs in demanding environments.
Yes. The product specifications indicate REACH environmental compliance, aluminium shell construction, and cadmium plating, all supporting durability and regulatory alignment in many industrial and defense installations. This makes it suitable for environments with exposure to temperature extremes and potential chemical exposure, while maintaining reliable electrical performance.
The 85100E2232PZ50 is a square flange receptacle with Z orientation intended to mate with corresponding Souriau/SI-standard square flange plugs designed for MIL-DTL-26482. The backnut option provides straightforward retention, and the 1/3 bayonet coupling ensures secure engagement. Always verify the exact part family and cavity arrangement to ensure 32-way compatibility.
Performance benefits include reliable 32-contact electrical performance, robust mechanical retention, and good EMI shielding due to aluminium shell construction. Cadmium plating offers corrosion protection, contributing to longer service life in challenging environments. For maintenance, plan for periodic inspection of the solder cups and mating interface, and ensure proper cleaning methods to preserve contact integrity.
