Rectangular connectors are one of the most widely used types of connectors in the electronics industry. They come in a variety of sizes, configurations and construction materials, and are used in a variety of applications including consumer electronics, automotive, aerospace, industrial, medical and military. The 71991-319LF connector is one such type of rectangular connector, and it has specific uses and working principles that make it ideal for some applications.

The 71991-319LF is a female, right angle connector whose body is made from a polyamide 6/6 flame retardant and UL 94V-0 rated material. It is a surface mount connector in a 2.00 mm (.0787 inch) pitch, single row format, with a snap-in mounting tab mechanism. The 71991-319LF is a low profile design which has a total height of 1.80 mm (0.071 inch) above the board, and its body measures 4.20 mm (0.165 inch) x 3.70 mm (0.146 inch). This low profile design makes it ideal for use in LCD flat panel displays, and other limited space applications.

The connector also features standard SMT feet with a dual post construction for maximum pad control and easy solderability, and a longitudinal retention feature for superior retention strength. It also has an 8-circuit configuration with a signal current rating of up to 0.2A and as much as 18V AC/DC. It has a UL Y-rated temperature and current, and the contacts are 20 micro-inches gold over nickel plated.

The 71991-319LF connector, with its low profile construction, snap-in tab mechanism and secure longitudinal retention feature, is especially designed and optimized for use with panel applications, where limited space is a requirement. It is ideal for ergonomic design in industrial control systems, computer applications related to displays, appliances and other applications.

The working principle of the 71991-319LF connector is quite simple. It involves the insertion of a header into the female socket of the connector, where the header pins protrude from the female socket and establish electrical contact with the connector. This creates a mechanical interlock between the header and the socket. The connector is then soldered onto the circuit board to create an electrical connection between the board and the connector pins, and the connection is complete.

The 71991-319LF connector has a long history of reliability and consistent performance in a variety of challenging applications. Its reliable and rugged construction, combined with its low profile and snap-in tab designs, makes it an ideal choice for applications where space is at a premium and increased reliability over time is a must.
