Rectangular Connectors - Headers, Male Pins, 281285-1 Application and Working PrincipleRectangular connectors are electronic connectors, widely used in different electrical and electronic assemblies. They come in a variety of sizes, designs, and configurations, and can be made from either metal or plastic. Male pins, headers, and 281285-1 are three common types of rectangular connectors. They have different applications and working principles, which are described below.Male PinsThe male pin is especially popular in the world of electrical connectors. It is a solid pin with a cylindrical shape, usually with a collar or groove near one end. The pin is often inserted into a socket or backplane that has female pinholes, allowing a variety of electrical connections between the two pieces. Male pins are suitable for lower current applications as the contact between the pins and the holes can be disrupted by high vibration and changes in temperature.HeadersHeaders are a type of rectangular connector that utilizes male pins and sleeves. The pin is usually coated with a thin insulator, protecting it from any testing current. The pins are then inserted into a plastic housing that forms the header. The plastic housing contains an array of pins that make contact with corresponding female pinholes. Headers are well-suited for high-throughput applications as the pins are unlikely to get disturbed and each connection is completely self-contained.281285-1 Connectors281285-1 are one-piece, board-to-board connectors designed for application in the automotive industry. They are composed of a plastic housing with two metal pins that are spaced out by an insulator. The pins have to be soldered on the other board. These connectors are particularly useful for connecting boards together in the industry due to their simple construction and the fact that the pins do not require any additional insulation.ConclusionRectangular connectors come in a wide variety of designs and configurations, suitable for different applications. Male pins, headers, and 281285-1 connectors are three common types of rectangular connectors that each have their own application and working principles. Male pins are good for lower current applications, headers are good for high-throughput applications, and 281285-1 connectors are typically used in automotive industry applications.
