2.92mm Product Specifications
The Johnson 2.92mm Series Connector provides an excellent solution for demanding applications requiring high frequency transmission. 2.92mm connectors have a smaller internal body diameter than SMA, utilizing an air dielectric. Precision manufactured for superior electrical performance to 40GHz. Connector mating interface per IEC 61169-35, and intermateable with 3.5mm and SMA connectors. Female contacts in Jack connectors have a unique three-slot construction, which enhances connectivity by creating a more rugged connector while reducing the chance of intermittent connections. The field replaceable jacks are teamed with a high quality hermetic seal feed thru for use in sealed circuit modules. The plug connector VSWR is 1.20 maximum to 40GHz and a 12 inch 2.92mm plug to plug cable assembly performs better than 1.35 VSWR to 40GHz. The 2.92mm plug interface employs more precise dimensions than an SMA and uses a shorter snub nose male pin such that the connector bodies align before the contacts engage. Precise assembly tooling assures excellent, repeatable contact and support bead location on cabled connectors. Available in screw on type and solder type end launch, 2 hole and 4 hole flange mount styles.
