Rectangular Connectors - Headers, Receptacles, Female SocketsRectangular connectors are the most popular type used in the electronics industry due to their low cost, high current carrying capacity and wide range of available, inclusive accessories. The 89891-342H is a high-density, 2 row, 3.96 mm wide rectangular connector. It has 2.54 mm pin-grid-array (PGA) with gold plated and polarized contacts suitable for power management applications and has a high current rating of 15 amps.The 89891-342H has a clear, symmetrical design, which ensures easy and secure mating that is short and narrow compared to comparable higher density connectors. It can be terminated by lead-in wire, solder on tail, or crimp contacts. The connector is RoHS compliant and is UL recognized.ApplicationsThe 89891-342H is primarily used for power management applications, where it is frequently used to provide power to many different devices with two physical ports. It is also used for industrial automation, data communication, and consumer electronics applications. Additionally, it can be used as a means to connect various computer peripherals, such as printers, monitors, and scanners.Working PrincipleUsing two physical ports, the 89891-342H connector is able to transmit and receive electrical signals and power. The two ports consist of a header on one side and a receptacle, or female socket, on the other side. The header is the male side of the connector and contains pins that make contact with the female contacts on the receptacle when the connector is inserted. The contacts on the female socket are chilled in order to create a good contact with the pins on the header side of the connector. The pins on the header side are gold-plated to ensure reliable and corrosion-resistant connections for repeated mating and unmating.ConclusionThe 89891-342H high-density connector provides a convenient solution for powering multiple devices with two ports. Its clear, symmetrical design ensures easy and secure mating with a high current rating of 15 A. The gold-plated contacts on the header side ensures reliable and corrosion-resistant connections for repeated use, and is RoHS compliant and UL recognized. The 89891-342H is ideal for power management applications, industrial automation, data communication, and consumer electronics.
