10-89-4202 Rectangular Connectors – Headers, Male PinsRectangular connectors – headers, male pins are a type of electrical component featuring electrical contacts with a rectangular, or other geometrically-shaped body with one or more slots to accommodate mating components. Typically, such headers include contacts to allow another wire or PCB-mounted component to be connected. In addition, the ‘Male Pin’ family of connectors offer the right angle structure and the space saving advantage due to the pins being mounted on the board.Application FieldThese connectors are widely used for a variety of industrial and commercial applications. The most common use is for board-to-board or cable-to-board connection. They can also be used for high-density interconnections, as they feature several cable exit ports for clean panel layout.Typical applications are:• Industrial Control Systems: These are the most common, and are mostly used to interconnect a variety of signal connections between different controllers, such as motion controllers, power supplies, and PLCs.• Telecommunications and Networking: Connectors are also used in high-speed data transmission, such as Ethernet boards or routers. They also can be used in CAT5/6 cables that are commonly connected to internet routers.• Medical and Automotive: This type of connector is often found in automobile chassis, medical consoles and in diagnostic equipment and surgical devices.• Robotics and Automation: Automated machinery and robots frequently use these connectors to link up the different boards and components.• Computer and Consumer Electronics: Connectors are also used in consumer electronics, such as computers, speaker connectors, audio/video and consumer electronics.• Instrumentation: Connectors are often found in industrial instrumentation, linking digital panel meters and LEDs for various measurement and display functions.Working PrincipleIn general, male pin connectors are used in conjunction with a mating female connector. Typically, the male pin is inserted into a hole in the female connector, and then a locking mechanism engages with the pin to hold it in place. This locking mechanism can be either mechanical or electromagnetic.Mechanical locking mechanisms are typically used for connectors that need to carry high current, such as in power applications. These include latching mechanisms, screw locks, snap-locks and lever locks.Electro-mechanical locking mechanisms are used in low-current applications, such as audio or data signals. These include solderless connectors and magnetic locking mechanisms, which use an electric field to hold the pin in place instead of relying on mechanical force.When two connectors are mated, the contact pins are exposed to HV, or high voltage, current. This can require specialized materials, such as varistors, ceramic capacitors and thermistors that are used to pass the current and protect the contacts from being damaged.In addition, connectors can be plated with metals such as tin, nickel, and gold to ensure superior electrical connections and mechanical strength. This can also help protect against corrosion, and ensure the contacts remain strong and secure over long periods of time.ConclusionRectangular connectors – headers, male pins are commonly used for various industrial and commercial applications requiring high performance, reliable connections in cramped spaces. They provide a high-density and easy-to-install way to connect different machines, controllers, and other devices together. With a variety of locking mechanisms and plating processes, these connectors are designed to be reliable over long periods of time.
