Product details

This is the reduced-diameter Mini BNC variant — smaller than a standard BNC — which saves panel space in dense video patch bays while maintaining the same 75 Ohm impedance. Rated to 2 GHz, it covers standard-definition and some HD-SDI video signals. The kit includes the connector body, an end cap, and a ferrule, all in a single tray package.

Termination and construction

The centre contact is brass with gold plating and is solder-terminated to the RG-179 centre conductor. The shield is crimped via the included ferrule — a standard field-termination method that gives a gas-tight connection to the braid.

Frequently asked questions

What is the replacement for 1274566-3?

No official replacement or successor order code is recorded for the 1274566-3. For new designs, a full re-qualification of an alternative Mini BNC or standard BNC connector for RG-179 cable would be necessary.

Does 1274566-3 come with end cap and ferrule?

Yes, the 1274566-3 is supplied as a kit including 1 connector, 1 end cap, and 1 ferrule — everything needed to terminate one RG-179 cable end.
