The 1-776261-1 is a vertical PCB header connector from the AMPSEAL product line designed for sealed, high-reliability connections in industrial and commercial transportation applications. This 14-position connector features gold-plated brass contacts with a 1.3 mm contact beam system and is rated for currents up to 17 amps, operating reliably across a temperature range of -40°C to +125°C. The connector incorporates a silicone rubber wire seal and glass-filled PBT housing to maintain environmental protection, with an insulation diameter range of 1.7–2.7 mm (16–20 AWG wire support). The design includes keying options and is suitable for applications requiring robust mating cycles (up to 600 cycles per hour) and high insulation resistance (100 megohms minimum), making it ideal for sealed automotive and industrial harness assemblies.
