It uses a 0.100" (2.54 mm) pitch, which is the standard grid for legacy and general-purpose PCB layouts, and mates with matching 0.100" pitch IDC sockets or receptacle strips.
The 5 A rating is typical for signal-level board-to-board duty — adequate for logic-level power or I/O lines, but not for bus-level current. This is standard for BERGSTIK II and works well for internal board stacks where the connector is not subject to cable strain or vibration. The overall contact length of 1.238" (31.45 mm) breaks down into a 1.043" (26.49 mm) mating length and a 0.095" (2.41 mm) solder post, which sets the board-to-board spacing when mated with a standard receptacle.
