The 103 rising clamp terminal family provides single-row screw connections in two pitches: TB25-103/5.0 at 5.0mm and TB31-103/5.08 at 5.08mm. The angled housing presents the wire openings and screw access above the board. Both models support 2–24 poles; their solder-pin widths and tail tolerances differ.
