Board-to-wire header with positive locking
The 5-1747072-2 is a 2-position, single-row header from the TE Grace Inertia GIC series, designed for board-to-cable/wire applications. Its 2.50 mm pitch sets the PCB footprint and confirms the mating half — a Grace Inertia receptacle with the same pitch and latch-compatible housing. The full 4-wall shroud protects the square male pins during handling and mating, reducing the risk of bent contacts in harness assembly.
Locking and environmental fit
In equipment that sees vibration — conveyors, pumps, portable devices — this latch prevents the connection from backing out.
Current rating and contact finish
The current rating is listed as 'Varies by Wire Gauge' — the actual current capacity depends on the wire size used in the mating receptacle and the temperature rise allowed. The tin-plated mating surface is suitable for moderate mating cycles and lower-cost applications; it does not offer the corrosion resistance or cycle life of gold plating. The through-hole termination with tin-plated posts is straightforward for wave-solder assembly.
