Product details

Two BNC Jacks in One Panel Cutout

The Amphenol RF 031-6578 is a dual-port BNC jack — two female sockets in a single zinc die-cast body, saving one panel cutout and the associated hardware compared to using two separate jacks. Each port is a standard BNC bayonet-lock interface, accepting the common male BNC plug found on 50 Ohm coax cables.

Mounting and Termination — Panel Fit and Solder Connection

The body is zinc die-cast with a nickel finish, giving a durable, corrosion-resistant shell that also provides consistent RF shielding.

Why Two Ports Matters — Panel Density vs. Single-Port Peers

The 031-6578 carries two BNC jacks in one body. Compare that to the single-port 031-5538-10RFX or 31-5640-1010 — both are otherwise nearly identical (same 50 Ohm impedance, 1 GHz bandwidth, 500 V rating, nickel body, gold center contact). The two-port version halves the panel cutouts and the nut-and-lockwasher hardware per signal pair, which matters when you're populating a 16-port or 24-port panel.

Frequently asked questions

Does 031-6578 come with a mounting nut or hardware?

The 031-6578 is a bulkhead-mount jack that requires a front-side nut and lockwasher for panel installation. The connector itself includes the threaded body for the nut; the nut and lockwasher are typically included in the package, but verify with the supplier at time of order as packaging may vary.

What is the replacement or equivalent for 031-6578?

There is no direct replacement or equivalent for the 031-6578 because it is a 2-port BNC jack. Single-port alternatives like the 031-5538-10RFX or 31-5640-1010 share the same 50 Ohm impedance, 1 GHz bandwidth, and 500 V rating, but require two separate connectors to replace one 031-6578.
