Product details

It is a 1-port connector built for the AT&T 735A cable group, with a crimp termination on the shield and a crimp contact. This is a smaller-profile BNC variant — the 'mini' form factor saves panel space while keeping the bayonet coupling that field techs rely on for a quick, vibration-resistant mate.

The Kit Contents — What Ships in the Tray

This order code ships as a 3-piece kit: one connector body, one contact, and one ferrule. The tray packaging means you get the parts ready for the bench — no separate sourcing for the center pin or the crimp ferrule. For a harness builder, this is a time-saver: one line item on the BOM covers the whole connector assembly.

RF Performance and Cable Match

The 75 Ohm impedance targets video and broadcast signal paths. The 2 GHz bandwidth covers standard-definition and most high-definition analog video signals. The specified cable group is AT&T 735A, a 75 Ohm dual-shielded coax.

Obsolete — Sourcing Reality for the 1274568-1

The 1274568-1 is listed as Obsolete. If you are designing a new panel layout, look at current-generation 75 Ohm mini BNCs from TE or Amphenol RF that match the same bulkhead cutout and bayonet lock pattern. For a legacy repair or a last-time-buy, the RFQ is the way to secure stock before it dries up entirely.

The gold-plated center contact handles the wear; the nickel body finish resists corrosion in indoor equipment racks. For a permanent install that gets mated once and left, the cycle life is overkill, but it means the connector will hold up if the panel gets reconfigured.

Frequently asked questions

What cable does the 1274568-1 terminate?

The 1274568-1 is specified for the AT&T 735A cable group, a 75 Ohm dual-shielded coax. It uses a crimp termination for both the center contact and the shield ferrule. If you are using a different 75 Ohm cable like RG-6 or RG-59, verify the cable OD and dielectric diameter match the connector's dimensions before ordering.
