The M902-2193 is a backshell accessory designed for DEUTSCH HD10 series 9-cavity threaded connectors, specifically engineered to accommodate cable diameters from 0.430 to 0.570 inches. Constructed from PC/PET polyester blend material with UV stabilization and flame retardant properties, this backshell is rated for continuous operation across a temperature range of -40°C to +134°C and meets UL94-VO flammability and UL746C weatherability standards. The rigid, durable design provides high-level cable protection, strain relief, and improved connector aesthetics by screwing directly onto the threaded HD10 connector body. This backshell is commonly paired with compression nut M902-2053 for secure cable termination and is widely used in industrial and commercial transportation applications requiring robust environmental sealing and mechanical support.
