CIRCULAR CONNECTORS- In a 20-page, full-color brochure, the Breech-Lok MIL-C-38999 Series IV circular connectors are detailed. The connectors are said to provide rugged, fool-proof quick-disconnect operation. The brochure includes complete data on available materials and finishes; a contact part number cross-reference; general data and service ratings charts; and engineering drawings and dimensional information to simplify the selection process. The connectors meet or exceed all performance requirements of the MIL spec and offer optimal resistance to fluids, corrosion, shock, vibration and heavy rear accessory loads. In addition, they offer excellent EMI/EMP protection through grounding fingers located within the plug housing.
