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.","metaTitle":"Amphenol RF 031-6578 BNC Jack, 2-Port, 50 Ohm, 1 GHz","metaDescription":"Amphenol RF 031-6578 BNC jack, 2-port, 50 Ohm, 1 GHz max frequency.

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."},{"question":"What is the replacement or equivalent for 031-6578?","answer":"There is no direct replacement or equivalent for the 031-6578 because it is a 2-port BNC jack.
