The Stratos HMA expanded beam connector has become the harsh environment standard in optical connectivity for up to 4 ports in multimode and single mode technologies.

The HMC provides further miniaturization in this series.

By incorporating the very latest manufacturing capabilities and design, Stratos Optical Technologies has produced the smallest 4 channel expanded beam connector in the world with a diameter of just over 3⁄4 inch (21mm). The precision optical alignment system of both the HMA and HMC connectors creates immunity from water, mud, dust, oil and other contaminants.

The series is designed with hermaphroditic coupling, which eliminates the need for adaptors allowing for rapid and simple deployment, time after time.

The HMC retains the rarely needed product HMA/HMC family attributes of being easy to repair, making it perfect for high density and SFF applications.

The HMC is available in several variants for bulkhead mounting with D-Hole, Flange mount with industry standard XLR footprint, and Thread mount.
