The 10-821626-000 is a dummy receptacle shell designed to provide a stowage location for unmated Amphenol 97 or AS50151 series plugs. This accessory is equivalent to a standard size 28 receptacle but is supplied without inserts or contacts. It features a 1-3/4-18 thread and a four-hole flange for panel mounting, with mounting holes of 0.147 inches in diameter. By providing a secure anchoring point, it protects the plug from mechanical damage and environmental contaminants, ensuring the integrity of the connector when it is reconnected.
