The 71991-403LF is part of the family of rectangular connectors known as headers, receptacles, and female sockets. This device, commonly used in modern electronic circuitry, is a pass-through that enables signals or power to be directed from one circuit board to another. It comes in multiple form-factor options, including surface-mounted type (SMT) and thru-hole, as well as an array of color-code configs for more efficient tracking.

The 71991-403LF is a two-piece interconnect system, composed of a specific pin header and an integrated plastic housing. This two-piece design helps ensure that no part of the contact system is loose during initial implementation and long after installation. The pin header consists of a series of poles arranged parallel and lying directly on a circuit board. The pins provide the physical connection between the device and board. The mating plastic housing fits over the pins, with a retaining clip that keeps the header and housing together. This housing can help be an environmental or mechanical barricade, preventing any undesirable objects, debris, or liquids from entering and disrupting the connection.

The 71991-403LF is commonly used in applications such as laptops, medical technology, networking and communication technology, and automotive industries. The device is particularly useful in high-power circuity applications, where power signals can pass from one board to the next. Additionally, the 71991-403LF can be used in military-grade and aerospace supply chains due to its superior durability and resistance to the elements. For example, the device can protect against water, dust, and extreme temperatures.

The 71991-403LF has a simple yet effective working principle. Upon implementation, the pin header’s pins are inserted into holes on the circuit board. The retaining clip is then applied to the housing, keeping the two pieces in place. The plastic housing prevents environmental debris from penetrating the connection, and, depending on the configuration, the header can help identify the flow of power or signals. It is important to consider the multiple types of 71991-403LF’s available in order to properly apply it in each application. This two-piece combination ensures a reliable connection in any electronic apparatus.

The 71991-403LF is a multifunctional device in the family of rectangular connectors. Its two-piece design helps to establish reliable power and signal transmissions in various applications. The device’s pins are inserted into a circuit board, and the plastic housing covers them for optimal protection against environmental hazards. With its durable properties, the 71991-403LF is well suited for military-grade and aerospace products. Its simple working principle enables the device to sustain the flow of power or signals for long-term applications.
