The 031-70542: The bayonet lock gives the quick quarter-turn mate typical of BNC, and the nickel-plated zinc die-cast body resists corrosion in field-installed runs.
Frequency, Impedance, and Cable Fit
The 4 GHz ceiling is the connector interface limit — the actual system bandwidth depends on the cable loss and assembly quality.
Termination and Mating Details
Both the shield and the center contact are crimp-terminated — no solder, no clamp. The gold-plated brass center pin handles repeated mating; the 500-cycle rating is typical for BNC and covers field reconnection without contact fretting. The bayonet lock engages with a quarter turn and holds the pair mated under light cable strain, though a cable tie at the back of the ferrule is the real pull relief.
