Rectangular Connectors - Headers, Male Pins

The 1969730-4 connector is a 4-way male header that provides one, two, or a three-position electrical connection between two points. It is a common type of rectangular connector used in a variety of applications ranging from signal transmission to power distribution.

Application Field

1969730-4 connectors can be used for various types of electrical connections, particularly for signal transmission applications. Commonly used in industrial equipment, consumer electronics, and airplanes, they are robust and reliable and feature a low profile design for convenience. They are often the ideal choice for internal wiring and external connections such as power supply in portable communication devices. Found in a wide variety of applications, 1969730-4 connectors are used to link PC boards to other components, machine panels to controllers, electronic power controllers to motors, and smart phones to accessories.

Working Principle

The 1969730-4 connector is comprised of two parts: the header, which contains the male pins, and the male pins themselves. The header is typically made of plastic and holds the pins, which can be soldered onto the respective boards or components. The header features four pins that make contact when mated with a corresponding plug or receptacle, creating an electrical connection.

1969730-4 connectors are designed to provide a reliable connection between two electronic components at low power. Electrical contacts are established when the male pins are inserted into the corresponding female connector, resulting in an electrical connection. The spring-loaded pins of the male connector ensure that the required connection is made with the mating female component, no matter how often the two components are separated and mated.

The number of contacts determined by the number of positions the connector supports: a three-position connector features three electrical contacts, while a four-position connector features four contacts. 1969730-4 connectors are often available in two and three-position variants to accommodate specific needs. The contacts of the connector are typically gold plated for improved durability and connection reliability.

Conclusion

1969730-4 connectors are versatile and commonly used in many applications, offering a reliable and economical solution for the efficient transfer of signals and power. The small profile and low profile design make them ideal for use in confined spaces, making them suitable for a wide variety of applications. With its robust contact construction, 1969730-4 connectors provide reliable and secure connections with a long life expectancy.
