Rectangular Connectors - Headers, Receptacles, Female Sockets have been a staple in the electronics industry for decades, with the 89891-315LF being a common and versatile connector of choice. In this article, we\'ll explore the 89891-315LF application field and working principle, and how it can be used in various settings to meet the needs of industrial, commercial, and consumer electronic devices.

The 89891-315LF Connector

The 89891-315LF connector is a flat ribbon type device incorporating multi-point connections along a thin profile. It utilizes two flat circuits. One is a high-density , high-cycle, low insertion force system, and the other is a low-density, low-cycle system. The copper alloy contact tails are eutectic brazed to the printed circuit board to form mechanically strong electrical connections. No additional soldering is required.

The 89891-315LF connector is polarized and has both male and female versions. The pin type is parallel pressed and spring-free with positive retention during insertion. It is available in 2, 3, 4, 5, 6, 8, 10 or 12 contacts. It has a high current rating of 30A and voltage rating of 450V AC, and can handle temperatures from -40°C to +105°C.

Applications and Uses

The 89891-315LF connectors are widely used in wide variety of settings. They can be used in medical and industrial electronics, automotive electronics, computers, communications systems, power systems, and many other device applications. The 89891-315LF’s versatility, reliability, and dependability make it an ideal choice for low-cost, multi-pin connections in a variety of industries and devices.

The 89891-315LF connectors can be used to support different signal and power levels for power, audio, medical/laboratory equipment, and various measuring instruments. They can be used for high-frequency signal, hybrid, telecommunications, and antenna applications with a frequency range of up to 10 GHz depending on the size and contact configuration. They can also be used for automotive power and lighting solutions in the automotive wiring and service of body electronics. In addition, they can be used for high-density flat signal and data communication in consumer and commercial electronic systems, including motherboards, wearables, and telecommunication products.

Working Principle

The 89891-315LF connectors’ primary function is to provide a secure electrical connection between two components or devices, while allowing them to be removed and reattached. This is achieved by combining the two flat circuits available in the connector, and utilizing the two contact tails of each that are securely soldered to the printed circuit board. These contact tails are then pressed together in order to form a positive electrical connection.

The 89891-315LF connector also features a plastic lever, which helps to ensure secure contact and a good connection. This lever is released by unrolling or extending the contact portion of the connector, allowing for easy removal of the connector. Additionally, the contact portion of the connector is designed with a small profile, allowing it to fit securely into tight spaces.

Conclusion

The 89891-315LF is a versatile, reliable, and dependable connector with a high current rating. It provides a low insertion force, making it suitable for low-cost, multi-pin connections in various industries and devices. Additionally, its two flat circuits and lever design allows for a secure electrical connection that can easily be removed and reattached.
