The adapter is built around a nickel-plated zinc body with a panel mount bulkhead feature, and the center signal path uses gold-plated phosphor bronze contacts, female on both ends.
What the 50 Ohm Rating Means for Signal Path Fit
The 50 Ohm impedance matches the characteristic impedance of standard BNC-terminated coax cables. A 50 Ohm adapter in the signal path preserves the impedance match from source to load.
Mechanical Installation — Panel Mount Bulkhead
The straight body style means the two BNC jacks align on opposite sides of the panel, giving a straight-through signal path. The bayonet lock fastening on both ends provides a quick quarter-turn mate with standard BNC plugs.
