AEC Series Accessories

Dust caps and boots are available for use with AEC series connectors. Te dust caps are designed to help provide protection to the connector interface when the connector halves are not mated. The boots are aesthetically pleasing and provide increased protection from dirt, paint overspray and pressure washing.

Dust caps are available for 40-way receptacles or plugs, available as either environmentally sealed or non-environmentally sealed.
