The 10-820073-28S is a MIL-5015 style straight plug from the Amphenol 97 series, designed for general duty interconnect applications. It features a solid aluminum alloy backshell (shell size 28) with a standard olive drab cadmium finish for durability. This connector houses a 28-21 insert arrangement with 37 non-rotating, silver-plated socket contacts (size 16) for solder termination, set in a hard diallyl-phthalate dielectric insert. It utilizes a threaded coupling mechanism for secure mating and operates reliably in temperatures ranging from -55°C to +125°C. As a versatile and cost-effective solution, it is widely used in factory automation, robotics, machine tools, and welding equipment.
