Product Description

Product Description

Applications

Features

The SMA 905 and SMA 906 connectors are designed for demanding applications that require a robust and reliable connection. Built with stainless steel or nickel-plated brass housings, they provide superior performance in harsh environments like military operations, medical systems, and industrial automation.

These connectors support both single-mode and multimode fibers and use a threaded coupling mechanism to ensure excellent vibration resistance. The SMA 905 features a straight body, while the SMA 906 includes a step-down design for added versatility.
