2-5102321-1 is an AMP-LATCH or IDC header connector designed for signal-level interconnect applications. It features a 0.100 x 0.100 inch grid spacing and is rated for 250 volts AC with a maximum current of 1 ampere per contact for signal applications. The connector operates over a temperature range of -65°C to 105°C and meets insulation resistance requirements of 5000 megohms minimum initial and 1000 megohms minimum final. It is designed to withstand 1000 volts AC at sea level and provides reliable contact retention under axial loads. Common applications include PCB interconnections where low-profile header assemblies are required.
