At increasing data transfer rates and operating frequencies it becomes increasingly important to safeguard the function of electrical devices and systems in their interactive relationship so that operation can be free of interference. In applications where connectors penetrate shielded enclosures commonly represent a breakdown in shielding since the connector’s plastic isolating body provides no shielding against any interference signals that may be present. CONEC filter connectors contribute to the protection of EMC zones. The intergrated filter (C, LC, Pi-Filter) inside the connector saves PCB-space and can be installed into an existing PCB layout. To replace an unfiltered connector into filtered one issimple and effective. D-SUBminiature connectors as a standard layout, high
density, combination or as adapter provide favourable conditions for equipping interface applications with different filter elements.
