RJ-45 CAT5 and CAT6 38999 Connectors


The Stran Technologies high speed RJ45 connector system incorporates a MIL-DTL-38999 series III derived metal shell with full 360 degree EMC and mechanical protection and has been designed to meet the requirements of high speed data connections where reliability through environmental sealing and full mechanical protection are required.

This product shares the same 38999 series III shell size 19 panel cut out and mounting dimensions as Amphenol.  Featuring an extended shell profile to match Amphenol dimensions while providing full mechanical protection of the RJ-45 insert. The insert is then fully potted to provide enhanced mechanical and environmental performance.  The original version of our ruggedized RJ45 Ethernet connector systems and now very popular in Aluminium Bronze and Stainless Steel shells, for the most demanding mechanical and environmental applications
