68458-104HLF rectangular connectors, also known as headers, male pins, are a common type of electrical connector used in many products. They are designed to provide a secure electrical connection between two components in a compact, easy-to-assemble package. 68458-104HLF connectors are particularly useful in applications where a signal needs to be sent through a limited-space environment, such as automotive, medical, and aerospace electronics.

The 68458-104HLF connector features a two-part housing and two separate pins. The housing is made of high-density Polybutylene Terephthalate (PBT) and is injection-molded to provide maximum support for the pins. The pins are made from a nickel-plated brass alloy and are designed to provide a reliable electrical connection. The pins are rated for 10 amperes, 250 volts, and can support temperatures as low as -55°C to 125°C. Additionally, the 68458-104HLF connector has a UL flammability rating of UL 94V-0, meaning it is highly resistant to fire and flames.

Working Principles

68458-104HLF connectors use a 4-way polarizing tab system to ensure proper mating and connection. The tabs are designed to fit securely into slots in the bottom of the connector housing, creating a secure connection between the components. The pins of the connector are shaped to form a “keyway,” or a notch, that prevents the pins from being inserted into the wrong slots. This keyway, along with the polarizing tab system, prevents electrical shorts and contacts from being damaged when the connector is mated.

When the connector is inserted into the mating part, the polarizing tabs click into place and the pins are securely locked in the correct slots. As the connector is tightened and the pins make contact, they create a strong electrical connection. This connection is further protected by the high-density PBT housing, which securely encloses the pins and provides additional insulation and strain relief.

Application Field

The 68458-104HLF rectangular connector is used in many different applications, including automotive, medical, aerospace, and industrial electronics. In automotive applications, this connector is used to connect electrical components in a variety of systems, such as headlights, power windows, and audio systems. It is also used in medical equipment where its compact size and secure connection make it an ideal choice for applications such as pulse oximeters and portable ECG systems.

The 68458-104HLF connector is also used in many aerospace and industrial applications. Its ability to stand up to high temperatures and pressures make it a popular choice for use in oil and gas exploration, as well as in down-hole equipment. Its reliability and robust construction make it a good choice for applications with stringent requirements and high vibration conditions. In industrial applications, it is commonly used in sensors, PLCs, motors, and other applications requiring a secure electrical connection.
