The AHDP06-24-21SR-BRA is a heavy-duty, plastic circular plug from the DuraMate AHDP series, designed for harsh environment applications. It features a size 24 shell with a 21-position insert arrangement, containing six size 12 socket contacts rated for 25A and thirteen size 16 socket contacts rated for 13A. This connector provides a robust IP68/IP69K environmental seal when mated, utilizing high-temperature silicone seals for protection against fluids and contaminants. The design incorporates a secure circular bayonet locking system, a reduced diameter rear seal for specific wire sizes, and a Backshell Ring Adapter (BRA) for compatibility with industry-standard snap-on backshells. Its durability and high-density configuration make it ideal for off-road, transportation, and industrial interconnect systems.
