Rectangular connectors are one of the most commonly used connection systems in all kinds of electronic applications. 71922-139LF is a type of rectangular connector with both vertical and horizontal mounting designs. It is used to connect industrial/automation, assembly, and communication equipment, linking two or more components in a uniformed physical and mechanical connection. This kind of connector is a type of header, male pin, featuring a right angle contact in a rugged housing.

The 71922-139LF is a two-piece connector consisting of a receptacle and a pin header made of UL 94V-2 rated flame retardant. The pin header features eighteen straight pins with DLK nibs, and consists of brass mate, stainless steel external cover, and thermoplastic insulators. The receptacle features spring-loaded, gold-plated phosphor bronze female contacts and an overall robust design. It is further sealed to protect it from dust, moisture, and vibration.

This connector can be classified as a 2-row connector, featuring a 2mm pitch and a 0.4 mm centerline. Its standard current rating is 3 Amps per contact, with a voltage rating of 250 VAC per contact. The 71922-139LF is generally used as a single-ended connection, in which only the pin header is mated with a receptacle. It is also known to be reliable and flexible, and can be mated with different types of rectangular connectors such as flex tail and modular jacks.

The 71922-139LF is designed for high-density electrical applications in a wide range of industries, such as medical, automotive, industrial, military and data communications. Its two-piece design allows for fast and easy assembly, disassembly, and replacement. It can also be safely sealed with the use of a gasket to protect against vibration, dust, and contaminants. Some of the most common applications of this type of connector include machine control panels, industrial equipment, and communication equipment.

The working principle of the 71922-139LF rectangular connector is simple. It consists of straight pins, typically made of brass, or other metals, that are placed in specific holes in the receptacle and the pin header. When the two components are connected, the pins are securely held in place with the help of thermoplastic insulators. These insulators protect the pins against shock and vibration, and help ensure the connection stays secure. As the connection is tightened, the female contact grabs onto the pins, and the spring-loaded female contact ensures a secure and reliable connection.

The 71922-139LF rectangular connectors offer a great balance of reliability, flexibility and affordability in a variety of applications. It is robustly designed for high-density applications, and its two-piece design allows for fast and easy connection and disconnection. Its gold-plated contacts and UL 94V-2 rated flame retardant construction make it suitable for a variety of applications, while its low profile design and space savings make it ideal for space-restricted environments.
