4-1734598-9 is a High Performance Interconnect (HPI) connector header designed for wire-to-board applications with a 1.25mm centerline pitch. This vertical-mount header features DIP (through-hole) PCB termination and supports 28–32 AWG discrete wire, accommodating 2 to 15 positions with a base length of 4.25mm plus 1.25mm per additional pin. The connector operates at a maximum rated voltage of 125V AC/DC with a maximum current rating of 1.00A and maintains reliable performance across an operating temperature range of -25°C to +85°C. The header dimensions are 4.70mm height (Y) and 3.20mm width (Z), providing a compact footprint for space-constrained applications. This connector is ideal for signal and low-power routing in consumer devices, industrial equipment, automotive systems, and business/retail applications where cost-effective, compatible interconnection solutions are required.
