Product details

50 Ohm BNC Bulkhead Pass-Through, 4 GHz

The Amphenol RF 031-4803-RFX is a straight BNC jack-to-jack adapter, 50 Ohm impedance, designed to pass an RF signal through a panel or bulkhead without a change in connector series or characteristic impedance. 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.
