INTRODUCTION

Radiall Commercial SMA connectors are specially designed for applications where low installed costs are of the utmost

importance. They are easy, fast to assemble and reliable, and offer the perfect solution for high volume applications

requiring high level performance such as in civil telecommunications, datacommunications or test and measurement.

These Commercial SMA connectors are fully compatible

(interchangeable and intermateable) with all existing MIL

standardized SMA connectors. They feature the same

performance level except for mechanical characteristics

(life: 100 matings and coupling nut torque: 60 Ncm).

The coupling nut of the Commercial SMA connectors

features a special design which is different from the

standard SMA coupling nut as the tightening torque

is reduced.

The Commercial SMA series offers a wide range of solutions

which are for every standard coaxial exible or semi-rigid

cable as well as PCB models with traditional through-hole

pins or solder pads for SMT applications.

The relative position of the center contact into the interface

is mechanically guaranteed by the snapping of the insulator

inner shoulder into the groove of the center contact.

This design facilitates the captivation operation in contrast

to other designs, requiring two insulators to provide

contact retention.

It assures constant and perfect axial positioning of the

center contact into the interface.

Due to the captivation technique, these commercial SMA

connectors are shorter than multi-piece body connectors.

The cable connectors can be either fully crimped or

soldered/crimped, offering full exibility for high volume

industrial production with standard manual or pneumatic

tooling: fast and reliable

- The center contact can be either crimped or soldered

- The outer contact is attached to the cable by crimping

a ferrule

The design and materials used in the manufacturing of the

Commercial SMA series allow us to offer connectors at

competitive prices to suit a wide range of applications. The

connector body is manufactured in brass and the surface

plating is available in either gold or in BBR nish (Radiall

non-magnetic bright bronze surface nish).
