350-10-142-00-001000 Datasheet/PDFRectangular Connectors - Headers, Male Pins
Connectors and pins are important elements in a wide range of electrical and electronic systems. Rectangular connectors such as headers and male pins are the most common type of connector found in electronic systems. These connectors come in a variety of sizes, shapes, and configurations, and have a multitude of application fields and working principles.
Uses
Rectangular connectors can be used in a wide variety of applications. Common applications include computer circuit boards, automotive electrical systems, electronic equipment, consumer products, and industrial process control systems. In addition, they are used in high current, high voltage, and specialized connector applications. Common uses for rectangular connectors include:
- Connecting electrical components in circuit boards
- Providing a link between an electronic device and an external system
- Converting AC to DC power
- Connecting an external device or system to a computer or other electronic device
- Being used as an interconnect for signal and power
Types
Rectangular connectors come in a variety of sizes, shapes, and configurations. They can be classified based on the number of pins or contacts, the overall size of the connector, and the type of pin architecture it has. Common types of rectangular connectors include:
- Pin Headers: These connectors are typically used for connecting circuitry on printed circuit boards. They are made up of a group of individual pins which are soldered to the circuit board. The pins are usually arranged in either a single row or double row configuration.
- Male Pins:Male pins are an example of a unipolar connector consisting of a male pin that fits into a female socket or pin receptacle. They are often used as part of an electrical harness assembly.
- Right Angle Connectors:Right angle connectors are mainly used to connect two circuit board in a tight perpendicular alignment.
- Flat Socket Headers:Flat socket headers are a type of rectangular connector which have a broad base with pins arrayed in rows at both ends. This type of connector is commonly used in automotive and consumer electronics applications.
- Strain Relief Connectors: Strain relief connectors are designed to relieve strain on a cable or wire. These connectors provide a secure connection between a device and a power source.
- Multi-Pin Connectors:Multi-pin connectors have two or more socketed pins which can provide power, signal and data connections between two electronic components. These connectors are commonly used in aerospace, automotive, and industrial control applications.
Design Considerations
When selecting a connector for a particular application there are several design considerations to take into account. These include:
- Pin Configuration:The number of pins in a particular connector must match the number of pins in the device or system that it will be connected to. It is important to ensure that the pins are properly arranged and that the connector will fit the mating receptacle.
- Connector Quality:It is important to select a connector which has been manufactured to a high standard to ensure reliable and consistent performance. Connectors which are poorly constructed can cause frequent connection losses or produce an unreliable signal.
- Current Rating:The current rating of the connector must be sufficient to carry the required current without causing significant voltage drop. This is essential in minimizing losses due to current moving through the connector.
- Environmental Requirements:It is important to select a connector which is designed to withstand the environmental conditions where it will be used. This includes temperature, atmospheric pressure, moisture and humidity levels, and salt spray.
Conclusion
Rectangular connectors are versatile components which have a multitude of application fields and working principles. They come in a variety of sizes, shapes, and configurations and are used in diverse applications from consumer electronics to industrial automation systems. When selecting connectors for a particular application, it is important to consider factors such as the pin configuration, connector quality, current rating, and environmental requirements.
