An easy approach to EMI filters

Aerco’s filtered connector solutions from Oxley Developments meet the need for custom filtering without adding to the complexity of a project.

In most electronics systems there are electromagnetic challenges; to protect the system from dangerous electromagnetic interference signals and also to guard against unwanted emissions from the system. In applications ranging from aerospace and telecommunications to military and civil control equipment, filtered connectors are used to provide that protection.

In most design circumstances, specific frequency ranges must be filtered, so custom filters are required, however most applications also use standard connectors to interconnect equipment. The Oxley solutions supplied by Aerco can be delivered across many different mil-spec connector ranges including MIL-DTL-38999 and MIL-DTL-26482 as well as ARINC and D-type connectors. Options include filtered extensions added to standard connector shells or filters integrated into custom-manufactured shells.

When compared with alternative solutions, filtered connectors provide ease of assembly, a reduction in space and weight, and the ability to avoid having internal bulkheads in equipment.

These filter connectors are designed and manufactured at Oxley Development’s self-contained facility in the UK, with prototypes available on rapid schedules and production quantities being supplied through Aerco’s flexible stock-holding services.
