Product details

This means Amphenol RF will continue to support existing production and replacement demand for a period, but the part is no longer being actively marketed for new projects. For a new BOM line, an alternative should be identified.

Cable Fit and Termination — What You Get in the Kit

The cable group is explicitly listed as AT&T 734, 734A, and Belden 1505A — these are 75 Ohm coax cables with a specific dielectric diameter and braid construction. The center contact crimps onto the center conductor, the ferrule crimps over the braid and jacket. The shield termination is crimp-style, not clamp or solder, so the correct crimp tool and die set for Belden 1505A-class cable is required.

RF Performance and Environmental Range

Rated to 4 GHz maximum frequency with 0.2 dB insertion loss, this connector handles the full L-band and most of the S-band for video and telemetry.

Frequently asked questions

Is 031-80104 compatible with Belden 1505A cable?

Yes. The cable group listed for this connector includes Belden 1505A, along with AT&T 734 and 734A. The kit is designed to terminate that specific cable type.

Does 031-80104 include the contact and ferrule?

Yes, the kit includes three pieces: one connector body, one gold-plated center contact, and one crimp ferrule. Everything needed to terminate one cable end is in the package.
