Junior Expanded Beam connectors (HMA)


  • Junior Expanded Beam connectors (HMA) is suitable for a variety of applications in harsh environments. The hermaphroditic design allows the mating of two connectors without the need for any adapter, allowing the connection of more cables in one optical path. Expanded beam technology, which uses lenses to expand and collimate the optical signal, makes this connector less sensitive to dirt and debris.
