Rectangular Connectors - Headers, Male Pins - 647338-1 Application Field and Working Principle

Rectangular connectors are connectors generally designed for making connection between printed circuit boards (PCBs) and cable harnesses. They come in a variety of sizes, shapes, and styles and more often than not comprise of two mating components, headers and pins.

The 647338-1 by heavy-duty manufacturer TE Connectivity, is a rectangular board connector, designed as 2.54mm (.1 inches) pitch dual row header, ruggedized for power applications up to 10A per circuit, this ruggedized power connector system can be used for a variety of applications. It is suitable for attaching shielding cages and for applications involving high vibration and shock.

Application areas:

• Marine
• Medical
• Industrial Control
• HVAC
• Industrial Automation
• Military & Explosive Environments

The 647338-1 is a dual row, shrouded header connector that offers ruggedized inter-board power connections by using a face contact system with crimp terminals on one side and a board mounted socket on the other side. The two-piece mating interface ensures that the system is vandal and dust resistant. The socket housing is made of a nylon based materials that provides optimal sensitivity.

Working Principle:

The two-piece mating system of the 647338-1 connector from TE Connectivity makes it the ideal choice for power applications. The pin side of the connector has a face contact electrical interface, with crimp terminals at its terminals. Its contacts are also designed to be dust and debris resistant, making it a more robust product. This connector is also designed to be vibration and shockproof. At the female end of the connector, a board mounted socket with latch securement allows a secure connection between the two board mating pieces.

The 647338-1 ruggedized power connector from TE Connectivity can handle up to 10A per circuit, the dual-row header also has the unique capability of providing up to 30A per pin. The headers and pins are designed with an optimized interface that allows for easy mating and unmating of the two connectors even in harsh or tight working conditions. The header has a wide gap between the inserted pins that prevents short circuits and also reduces engagement force in high vibration conditions.

The 647338-1 connector is compliant with UL/VDE safety standards and also rated for use at temperatures from -40°C to 125°C. It is also RoHS compliant and suitable for use in hazardous areas as a UL approved connection.

Conclusion:

The 647338-1 from TE Connectivity is a robust, dual row header connector capable of carrying up to 10A per circuit and 30A per pin. Designed to be dust and debris resistant, this connector also offers protection against vibration and shock, making it suitable for a wide range of applications, including marine, medical, HVAC, industrial automation, industrial control, and military & explosive environments. Compliant with UL/VDE safety standards and rated for use at temperatures from -40°C to 125°C, this ruggedized connector allows for easy and secure mating even in harsh or tight working conditions.
