2.50 mm pitch, 13-position right-angle header for wire-to-board
The S13B-XASK-1 is a 13-position, single-row header from JST's XA series, on a 2.50 mm pitch, designed for board-to-cable/wire applications.
Press-fit and solder termination with board lock
Termination is listed as press-fit and solder, meaning the header can be pressed into plated through-holes without solder for a gas-tight connection, or soldered for a conventional joint.
13 vs 14 positions: S13B-XASK-1 and S14B-XASK-1
The S14B-XASK-1 is the 14-position sibling in the same XA series, sharing the same 2.50 mm pitch, right-angle orientation, locking ramp, board lock, and tin plating. If your BOM calls for 13 circuits, the S13B-XASK-1 is the direct fit; the 14-position version is a functional alternative if the extra position can be left unpopulated or if the mating receptacle is available in 14 circuits.
