 Raymond EMC offers a complete line of feedthroughs for passing R.F. and data through an R.F. Shielded Enclosure. Integrating an R.F. Connector or a Filtered Feedthrough into an R.F. Shielded Enclosure System requires the use of a Bulkhead Connector Panel to ensure optimum R.F. Shielding Effectiveness.
R.F. Connectors
Raymond EMC can supply virtually any bulkhead mount R.F. connector including standard and precision connectors.
Filtered Feedthroughs
Raymond EMC offers a line of D-subminiature filtered feedthroughs suitable for most data applications.

The integration of a D-subminiature feedthrough filter into an R.F. Shielded Enclosure System may reduce the overall R.F. Shielding Effectiveness of the System to the levels outlined in the table above. The actual reduction would depend on cable length and jacket shield type both inside and outside of the enclosure. |
