The nickel-plated brass body and gold-plated phosphor bronze centre contacts give this adapter the corrosion resistance and mating-cycle life needed for test-equipment panels, instrumentation enclosures, and RF distribution boxes where the cable run passes through a wall. Rated to 4 GHz, it covers the full BNC band for most lab and communications applications. ## Mounting Hardware Included No separate hardware order needed for the panel install — the lockwasher provides vibration resistance against the bulkhead face, and the nut secures the adapter from the rear. The bulkhead mounting feature accepts panel thicknesses typical of sheet-metal enclosures and RF chassis. ## 500 Mating Cycles with Gold-Plated Contacts The bayonet lock on both ends gives a positive axial mate without thread wear.","metaTitle":"Amphenol RF 031-4803-RFX BNC Jack-to-Jack Adapter, 50 Ohm","metaDescription":"Amphenol RF 031-4803-RFX BNC bulkhead adapter, 50 Ohm, 4 GHz max, 500 mating cycles.
