Rectangular Connectors - Headers, Male Pins 68438-172HLF Application Field and Working Principle

Rectangular connectors are a kind of PCB connector used for electrical connections between the PCB and external fine (or fine-pitch) components mainly used in the electrical and telecommunication industry. Rectangular connectors consist of a contact block, the housing and a latching notch. Nowadays, the use of connectors is quite common and widely used for any electronic device, but each type of connector has its own features, limits, and ranges applications, and some more than others. The 68438-172HLF rectangular connector is one of the most popular headers for use in a wide range of applications.

The 68438-172HLF is a two-row stackable male header connector with a total of 20 pins. The connector has an overall length of 21.05 mm (0.83 in) and the contact pitch is 2 mm (0.08 in). This connector is particularly well-suited to a large variety of applications due to its combination of 2mm pitch and compact size. It has the same compact length as the 20-pin 68438-172V product but with a larger number of pins.

The 68438-172HLF is a reliable solution for allowing multiple connections in a small space and it is suitable for power and data transmission. It carries up to 5A current per power contact, depending on the AWG cable gauge. It also offers superior EMC protection as it is compliant with the latest international standards. All contacts are heavily gold plated for maximum durability, low contact resistance and superior reliability. The 68438-172HLF is ideal for a wide range of applications, including medical technology, consumer electronics, automotive, industrial, telecommunications and other high-end applications.

The working principle of the 68438-172HLF is quite simple. The connector is designed with two rows of 20 pins each, with a 2mm pitch. Each row can easily snap to a PCB board. The terminals of the connector are designed to fit into the designated printed circuit board holes and make contact with the board. Then a locking notch fits into the latch of the housing to ensure secure contact and to prevent accidental disconnection. The contacts are gold plated to ensure signal integrity and to provide long-term reliability of connection.

Overall, the 68438-172HLF is an excellent choice when high performance and reliability are essential. With a small size and 20-pin capacity, it makes it suitable for a wide variety of applications, from consumer electronics to advanced industry applications. The gold plating specification ensures longevity and low contact resistance which make it ideal for both power and data transmission. The latch design prevents accidental disconnection during operation, making the 68438-172HLF a safe and reliable connector for many applications.
