Miniature Type and High Density Mounting These connectors are designed in a miniature and light weight product, and mounted in the high density. The crimping case is structured in the 2mm pitch grid, so that connectors can be arranged for use. 2. Variation in Number of Contacts In addition to the dip type, SMT and crimping types are available with broad variations. 3. Stacking Variation When the connector is used for board to board, set 6mm between boards in conjunction with the pin header A3B, or 5.1mm between boards in conjunction with the pin header A3C.
