Product details

The 031-71053: Rated to 1 GHz with a 0.2 dB insertion loss across the band, it carries composite video, HD-SDI, and baseband signals without the impedance mismatch that 50 Ohm parts introduce on a 75 Ohm line. The right-angle PCB tail and bulkhead front-side nut mount it flush to a panel, with the bayonet lock securing the mating plug.

500 Mating Cycles with Gold-Plated Centre Contact

The isolated construction (the centre contact is electrically separate from the shell) and the board guide on the mounting feature help align the connector during panel installation and prevent ground loops in sensitive video paths.

Frequently asked questions

What is the datasheet for the Amphenol RF 031-71053 BNC connector?

Design engineers need the datasheet to verify electrical and mechanical fit for their application.

How much does the 031-71053 cost?

Sourcing buyers compare pricing to meet budget constraints for BOM line items.

Where can I buy the 031-71053 BNC jack?

Transactional buyers need a reliable distributor with stock to place an order immediately.

Is the 031-71053 a 75 ohm or 50 ohm connector?

Impedance mismatch can cause signal reflection, so this specification is critical for RF system integrity.

What is the replacement for Amphenol RF 031-71053?

Maintenance techs and brokers need to know if a direct substitute is available if the part is obsolete or hard to find.

What is the insertion loss of the 031-71053 connector?

Design engineers must ensure the connector's loss budget meets system specifications for signal strength.
