89891-343HLF rectangular connectors are headers, receptacles, and female sockets with a 1.27-mm pitch, four-row contact footprint, and straight pin lengths of 2.50 mm. The half-pitch design with identical pin lengths and criss-cross contact pattern eases routing, making the 89891-343HLF suitable for a wide range of applications.

Application Field

These connectors are suitable for board-to-board bridging applications such as the cable-to-board connection of video game systems, communication equipment, and portable medical equipment. The 89891-343HLF is also suitable for use with computer systems, Thunderbolt A/I O products, telecom/networking systems, industrial control systems, motion-control systems, and consumer electronics.

Working Principle

The 89891-343HLF consists of a male header mounted to a printed circuit board (PCB) and a female socket attached to the cable. The male header has a metal shell with two blades and four rows of contacts arranged in a parallel array. These contacts are typically stamped-and-formed from phosphor bronze alloy (sometimes gold-plated) and plated with tin/lead to resist corrosion and wear. The two blades of the shell provide polarization and alignment.

The female socket has a plastic shell, four rows of contacts, and two retention clips at the end of the socket. The contacts of the socket are typically machined from brass with gold-plating to resist corrosion. The two plastic retention clips snugly hold the male header in place once inserted. The four rows of contacts on the female socket slide into the four rows of contacts on the male header to make the electrical connection.

Also included in the connector system are dust caps which protect the contacts from dust and debris and help to prevent damage such as short circuiting. Additionally, the 89891-343HLF’s low profile design (from 6.85 mm to 8.10 mm) makes it an ideal choice for use in high-density applications.
