XH2A-3041-A Omron

Half-pitch Board-to-Board Connectors XH2 Allows High-density Mounting for Electronic Devices. A Half-Pitch Connector with a 1.27-mm Pitch for Compactness. A pitch of 1.27 mm for high-density mounting of double-row arrangements. A quadruple-row staggered arrangement (1.27 mm x 1.905 mm) for board connection. Leaf contact construction enables smooth mating and resistance to bending. Space saving mating length of 3.1 mm. Press fitting assures long-term contact quality. The gold/palladium plating has been improved for better contact reliability. A special finish improves flux resistance (Straight Terminals only). Also it has fastening pins to stan- dardize all the contacts. Can be mounted to boards with screws. Not mated with XH3 and XH4 Half-pitch Connec- tors. See theStandards certification / conformity lis for information on conformity to certification standards.
