Product details

The 112957-11: This is the 75 Ohm variant of the standard BNC interface — not the common 50 Ohm type — so it is the correct choice for video distribution, HD-SDI broadcast, and precision instrumentation where the impedance match matters.

Cable Prep and Termination

Cable group is RG-6 double braid and Belden 1694A — the ferrule and centre contact dimensions are matched to these cable diameters.

Signal Path and Frequency Range

Rated to 6 GHz with 0.2 dB insertion loss. The 75 Ohm impedance and PTFE dielectric keep the signal path stable across the band.

Temperature and Environment

Frequently asked questions

What cable types work with 112957-11?

RG-6 double braid and Belden 1694A. The included ferrule and centre contact are sized for these cable constructions. For RG-6 quad shield, verify the cable outer diameter against the ferrule before committing.

What is the mating cycles rating of 112957-11?

500 mating cycles. The gold-plated centre contact supports this cycle life — suitable for field-service patch panels where reconnections are occasional, not daily.
