It carries 10 circuits in a single row at 2.50mm pitch, rated 3A per contact at 50V — typical for signal-level interconnects in control panels, sensors, and general-purpose equipment.
At 2.50mm pitch, the 10-position header occupies about 22.5mm of board edge (9 spaces × 2.50mm plus the outer walls). The mating half is a Signal Double Lock receptacle housing (TE series 917790 or similar) that accepts crimp terminals for 20-24 AWG wire. Compared to the 1-292164-1 from the CT series, this header uses a wider 2.50mm pitch versus 2.00mm, and carries 10 positions versus 11. The CT series runs at 125VAC versus 50V here, but the Signal Double Lock latch holder provides a more positive lock than the CT's detent lock — a meaningful difference if vibration resistance is the priority.
