640502-2 Rectangular Connectors – Headers, Male Pins

Rectangular connectors, commonly referred to as headers, are used in a wide variety of applications and are the most common type of connector used today. The 640502-2 header is a unique design and has become increasingly popular in the market. The 640502-2 header is designed specifically for large-scale applications, such as energy, industrial, military, and medical applications.

Application Field

The 640502-2 header was designed for applications that require a higher level of reliability and performance than traditional rectangular connectors. This type of connector is used in a variety of applications, such as industrial environments, where high vibration, prolonged exposure to chemicals, and harsh environments are present. This type of header is also perfect for energy industry applications due to its robust design. applications such as oil and gas exploration, where an airtight seal is required, have also benefited from the use of this connector.

Working Principle

The 640502-2 header is a combination of two main components, a header and a male pin. The header is typically soldered onto the PCB while the male pin is inserted into the back of the header. The two components are connected with threaded screws, flange nuts, or a latch type mechanism. The connection is then sealed with an o-ring to ensure a watertight and airtight seal. The electrical connection is made by contact between the two metal parts. The male pin typically has a copper or brass contact that is machined to fit into the header’s copper or brass contact. The contact is then soldered to the PCB for a strong electrical connection. Due to its robust design, the 640502-2 header is perfect for applications that require a reliable connection in a harsh environment. The header has become increasingly popular due to its superior performance and reliability. The o-ring seal allows for a watertight and airtight connection and its solder connections ensure a consistent electrical connection. The 640502-2 header is designed to withstand a variety of conditions and is the perfect solution for a wide range of applications.
