Board footprint and lock that keep the wire-to-board joint tight
The 1744428-2 is a 2-position, single-row header from the Economy Power series, with a 0.156" (3.96mm) pitch that matches the standard power connector footprint. It mates with a wire-to-board receptacle using a friction lock — no latch tool needed, just push until the ramp clicks. The single-wall shrouding protects the pins from casual shorts but leaves the top open for visual alignment.
Current, voltage, and temperature ceiling
The tin-plated contacts (80 µin on both mating and post) handle moderate mating cycles — fine for a power interconnect that isn't disconnected daily.
