The 350552-3 is a phosphor bronze pre-tinned socket contact designed for use in Universal MATE-N-LOK wire-to-board connectors manufactured by TE Connectivity/AMP. This contact is specifically engineered for 20-14 AWG (5.2-10 mm²) wire sizes with an insulation diameter range of 0.130-0.200 inches (1.80 mm), featuring a socket length dimension of 0.781 inches (19.80 mm). The contact utilizes phosphor bronze material with pre-tin plating to ensure reliable electrical conductivity and corrosion resistance in power circuit applications. These contacts are commonly used in home appliances, particularly gas appliances, where robust wire-to-board connections are required, and they support the connector's positive lock mechanism for secure mating.
