This header features a 2-position configuration with dimensions A = .084 [2.13] inches and operates on a .100 [2.54] centerline pitch. The header includes C = .120 [3.05], D = .230 [5.84], and E = .185 [4.70] dimensional specifications with Plating A contact finish. It is designed for through-hole PCB mounting with a recommended hole size of .036±.002 [0.91±0.05] for tin-plated boards. These headers are commonly used in board-to-board interconnection applications where reliable retention and breakaway functionality are required.
