Rectangular Connectors - Headers, Male Pins

Rectangular connectors, most commonly known as headers, are a type of electrical connector, which is composed of a physical barrier and several metal pins. The metal pins are arranged in a rectangular formation within the physical barrier, allowing an electrical connection between two separate parts through the insertion of a male pin. The 155226-5203-RA applied rectangle header is one of the most widely used in various industries due to its durable construction and reliable performance.

Constructional Features

The 155226-5203-RA rectangular header is constructed using an aluminium alloy connector with a standard male pin size of 2.54 mm. The electrical contacts are black plated with gold and feature integrated socketed locking ramps. The total connector height is approximately 20 mm and the mated height is about 15 mm. The connector has an operating temperature of -40°C to +125°C and a current rating of 5 A.

Application Field

The 155226-5203-RA rectangular header is suitable for low voltage and low current applications, such as those in office equipment and consumer electronics. It is also used in telecommunication and broadcasting devices for signal transmission. This header is commonly used in automotive and transportation as well.

Working Principle

The rectangular connector works based on the principle of electrical connections between two points. The electrical contacts, usually located on either side of the connector housing, provide a point from which electrical current can travel. When the male pin is inserted into the connector, it connects the contacts together, thereby allowing the electricity to flow between the two points. The contacts may be located within the housing itself, or may be externally mounted on a board.

Benefits and Advantages

The 155226-5203-RA rectangular header has several benefits that make it a popular choice for a variety of applications. It is designed for reliable performance and can withstand extreme environmental conditions. Moreover, the gold plated contacts may improve signal integrity and reduce contact resistance. This rectangular header is easy to assemble and features robust connector construction, making it suitable for multiple mating cycles. Furthermore, it allows for easy wire routing and has a low resistance port for improved signal transmission.

Conclusion

The 155226-5203-RA rectangular header is an ideal choice for various low voltage and low current applications. This durable and reliable connector is suitable for multiple mate cycles and can withstand extreme environments. It is designed for simple assembly and features gold plated contacts for improved signal integrity. Moreover, it allows for easy wire routing and has a low resistance port for superior signal transmission.
