Termination: Describes the shape or standard configuration of a device’s electrical connection(s). Mounting Feature: A modifier to how the item is being attached. Primarily applicable to jacks/receptacles. Internal Switch(s): Indicates if a device incorporates a switch actuated when a device is mated with a compatible connector. Number of Positions/Contacts: The total number of electrical conductors the device has. Industry Recognized Mating Diameter: Indicates nominal connector dimensions, as referenced for purposes of determining mechanical compatibility.Īctual Diameter: Indicates the true dimension of the mating portion of a device, as contrasted with an industry recognized mating diameter. ![]() Gender: Indicates the geometry of the mating surface of the connection. Various sizes are available, with inner diameter, outer diameter, and mating length of plug and jack needing to be compatible in order to achieve a proper connection.Ĭonnector Type: Indicates the style/format of the connectors used to connect this product. They are characterized by a tube-shaped plug having electrical contacts on the inner and outer surfaces. Power barrel connectors are most commonly used to connect low-voltage DC power provided from a wall mounted AC-DC converter to small electronic equipment, such as laptop computers and printers. Here is a list of crimp contacts for part 455-2266-ND which you will need to select the proper contact by the size wire gauge being used. Crimp contacts are not included with the inline connectors so be sure to include them with your order. Here is an option for a 2 position header, part 455-2247-ND, scroll down and you will see the inline mate to this would be part 455-2266-ND. When looking for a mating connector scroll towards the bottom of the page to the section that lists the “Mating Products” and select the option that best suits you’re needs. These lists show the vertical and right angle versions along with the option to select tin or gold contacts. These numbers, XH2.54-2 or XH2.54-3 are referring to the XH 2 position headers or XH 3 position headers. These are actually the XH series of connectors from JST available here at Digi-Key, XH Series connectors Often what you will see in the BOM (Bill of Materials) listed for a board will be numbers like JST XH2.54-2 or JST XH2.54-3 which is not the actual part number you would use when ordering, for example purposes you will see I used the -2 and -3 suffix which is simply calling out the number of positions on the header. XH2.54 connectors from JST: We have several inquiries about this connector since it is a commonly used pin header on power supplies, eval boards, etc. ![]()
