SSMA Female 4-Hole Flange Mount RF Connector – Field Replaceable, 5.9mm Hole Spacing, 0.46mm Pin Diameter

SSMA Female 4-Hole Flange Mount Field-Replaceable RF Connector – Model SSMA-KFD4

This SSMA female 4-hole flange RF connector combines a 0.46 mm pin with 5.9 mm hole spacing for higher contact area and rugged coupling. It supports 50 Ω systems from DC to 36 GHz and features a field-replaceable body for simplified upkeep.

Microwave-Ready Performance

Expect VSWR ≤ 1.25 and insertion loss ≤ 0.06 √F(GHz) dB to protect dynamic range and measurement repeatability in microwave chains.

Built for Dense 4-Bolt Panels

The 5.9 mm pattern maximizes port density while preserving mechanical rigidity—drop-in compatible with our 4-hole flange mount ecosystem.

Ideal Use Cases

Pick the 0.46 mm pin for mid-power paths, amplifier characterization, and ruggedized test sets where contact durability matters. Compare alternatives in our SSMA portfolio.

Materials & Lifecycle

Stainless shells with gold-plated BeCu contacts resist wear and corrosion over many mate/de-mate cycles; find compatible accessories in the RF Connector Catalog.
