<p>A housing for an optically coupled isolator is mountable through an aperture of an electromagnetic barrier. The housing includes a first recess in a first end for receiving an insulator and an optical driver device and a second recess in a second end for receiving an insulator and an optical detector device. A bore extends through the portion of the housing between the first and second recesses. Preferably, the bore has a length on the order of five times greater than its diameter which imparts waveguide characteristics for attenuating certain electromagnetic radiation. An outwardly extending flange of the housing has a groove in which a gasket is disposed. Preferably, the gasket is comprised of an electrically conductive material. In use, the gasket is compressed against the electromagnetic barrier and maintains electrical continuity across the barrier.</p> |
