EDAC, Inc. Edgeboard Connectors 345-042-544-204

The Card Edge Connector, Dual, 42Pos, Wire Wrap (part number 68AJ5204) features a 0.100,Äù (2.54mm) contact spacing and is designed to accommodate a nominal P.C. board thickness of 0.062,Äù (1.57mm). It is constructed with a UL 94V-0 thermoplastic polyester insulator and utilizes copper alloy for its contacts, which are plated with gold on the mating area and tin on the tails, with nickel underplating. The connector supports a current rating of 3 amps and has a maximum contact resistance of 10 milliohms. This connector is rated for a dielectric withstanding voltage of 1200 V AC rms and an insulation resistance of at least 5000 megaohms. It operates effectively within a temperature range of -40¬8C to +105¬8C. The connector offers various termination options, including P.C. tail and wire wrap, and is available in both single and dual row configurations. It also includes features such as automatic wire wrap positioning holes and is RoHS compliant. Engineers should consider this connector for applications requiring reliable electrical connections in compact spaces, particularly where dual row configurations are beneficial.
