644749-8

644749-8 are Headers, Male Pins, from the family of Rectangular Connectors. They are typically used to connect two cables or devices together, and are designed for reliability and high-performance signal integrity. It is suitable for use in severe industrial environments.

The 644749-8 consists of two pieces – a socket, in which the male pin is inserted, and a header, on which the socket is fitted. The header has two rows, usually made of copper alloy, with up to 75 positions (in 7.5mm pitch) per row and available in vertical and horizontal mounting styles. Most headers also have an integrated seal for dust and moisture protection.

The 644749-8 male pin is available in either 3-pin or 4-pin configurations and has a current-carrying capacity of 3A. It is typically constructed of copper alloy aluminum and features an insulated sleeve to protect the pins from accidental contact with other electrical components. The male pin is designed with a two-piece contact, allowing for a secure and reliable connection.

The 644749-8 is PIN-compatible with most existing Rectangular Connector applications and provides superior signal integrity and cable retention. Since its introduction, the product has been used in a variety of applications, including instrumentation, communications, and industrial automation.

The 644749-8 is designed to operate at temperatures ranging from -55°C to +105°C, and features a vibration resistance of up to 10G. It also passes MIL-STD-2150A for low-level RF immunity and is certified to CSA/CUS Generic Specification C22.2 No. 209-07 for superior environmental protection.

The 644749-8’s working principle is similar to other Rectangular Connectors. When the male pin is inserted into the socket, the two rows of copper alloy are joined together and the pin is held firmly in place. This creates an electrical connection that is reliable and secure. Additionally, the 644749-8 includes a dust cover to help protect the socket and pins from dirt and other particles, and a seal to ensure proper protection from moisture.

Overall, the 644749-8 is a reliable and high-performance connector suitable for a wide range of applications and environments. Its PIN-compatibility makes it an ideal solution for making connections between two devices or cables, and its robust construction and integrated seals provide enhanced signal integrity and superb environmental protection.
