40-Pin SMT Header on 0.100-inch Pitch
The 95157-440LF: Surface mount termination means the part reflows with the board in a single pass — no secondary soldering operation.
Unshrouded headers expose the square pins — no shroud to key or guide the receptacle. The board layout must provide the alignment tolerance; the mating receptacle (typically a BERGSTIK II socket or a standard 0.100" pitch IDC connector) relies on the pin tips for initial alignment.
