228226-1 is a BNC 50 Ohm bulkhead jack-jack adapter designed for RF coaxial connector applications. The adapter features a nickel-plated body with gold-plated center contact (Gold1 plating at 0.00127 mm thick) and polyethylene dielectric material for reliable signal transmission. Key dimensional specifications include a height (H) of 17.78 mm (700 mils) and length (L) of 36.07 mm (1420 mils), with a recommended panel cutout of 11/16 inch across flats and 20.32 mm across points. This bulkhead configuration is ideal for panel-mount applications in RF systems, telecommunications equipment, and test instrumentation where secure, shielded connections are required.
