Overview
Based on the arrangement of XCH type contacts, this series of products keeps various electrical properties unchanged, reduces the spacing between holes, and is smaller in size and lighter in weight than XCH type under the same number of cores; it adopts the bayonet quick connection method, which is fast and convenient to use. ;The jack contact is a wire spring jack structure with high reliability; it has a variety of metal shell structure forms and surface coating options, and has good environmental resistance; at the same time, the five-key positioning has the functions of blind insertion and wrong insertion, and the contacts are terminated The method is wire welding, with high contact density, equivalent to MIL-C-26482 series I. This series is widely used in aviation, aerospace, weapons, ships and other fields.
