Digi key connectors8/3/2023 ![]() Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Insulation Color: The color of the item/device’s main non-conducting body. And where applicable the type being used.įeatures: Special features or functions the device includes. Shielding: An indication of if the item has a layer of material that can block electromagnetic radiation/noise. Termination: Describes the shape or standard configuration of a device’s electrical connection(s). 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. Incoporation of switching functions may cause the two to differ. Number of Positions/Contacts: Indicates the number of distinct conductors presented at a connector’s mating interface and the number of electrical contact points present within a connector. 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. Signal Lines: Indicates the number of signal paths established between a mated connector pair. Gender: Indicates the geometry of the mating surface of the connection. Several standard (nominal) sizes are available, the most common being the 1/8" (3.5 mm) format commonly used for audio connections in desktop and mobile devices, and the older 1/4" (6.35 mm) size more commonly found on older or non-portable equipment where durability is of generally greater interest than minimal size.Ĭonnector Type: Indicates the style/format of the connectors used to connect this product. They are characterized by a cylindrical plug divided into two or more sections along its length and having an indented region near one end that is engaged by a spring loaded contact in a mating jack to provide retention force. Wire Gauge: The size of wire or range of wire size the item is designed to accept.Ĭontact Termination: Describes the shape or standard configuration of a device’s electrical connection(s).Ĭontact Material: Indicates the material from which a contact is fabricated.Ĭontact Finish: Indicates the contact surface material.Ĭontact Finish Thickness: Indicates the thickness of contact surface material.This Product Selection Guide contains information to help select products in the Audio Connectors category on Īudio barrel connectors are a style of connector most commonly used for connecting audio equipment such as headphones and small microphones. Pin or Socket: Indicates the geometry of the mating surface of the connection. To form the other half, contacts such as these are applied to the discrete wires to be connected, and inserted into an appropriate housing. This Product Selection Guide contains information to help select products in the Card Edge Connector Contacts category on Ĭard edge connector contacts are components of an interconnect system that facilitates connection of multiple discrete wires to a printed circuit board, using a copper pattern etched on the PCB as one-half of a mating connector pair.
