It uses a 0.157" (4.00mm) pitch on both the board and cable side, and mounts surface-mount, right-angle to the PCB. The Feed Through feature lets you daisy-chain signals through the connector without a separate jumper, which saves a splice point on the line.
The 0.157" (4.00mm) board-side pitch means the PCB footprint needs 4.00 mm between pad centres, not the more common 2.54 mm or 3.00 mm. The IDC termination punches through the insulation of 24 AWG wire — no crimp tool, no terminal to stock separately. You strip the wire, lay it in the slot, and press. That saves assembly time if you're building a few dozen boards, but the connection is permanent; you cannot re-pin it on site if a wire pulls out. The tin contact finish is fine for a one-time mate inside an enclosure, but if this connector sees repeated disconnect/reconnect cycles, the tin will fret and the contact resistance will drift.
