The more information you have or can find on a connector, the better.This Product Selection Guide contains information to help select products in the Coaxial Connector (RF) Accessories category on Ĭoaxial connector accessories are items used with coaxial cable connector systems, which serve ancillary functions such as sealing of a connector assembly, mechanical fixation, avoidance of accidental un-mating, protection of un-mated connectors, cable strain relief, and others.Ĭonnector Style: An indication of the type of connection being use. Other common features for connectors would be an ingress protection or IP rating, voltage rating, current rating, and other various ratings. The most common type is crimp, but other types would include solder, solder cup, IDC, or quick connect, depending on the connector. What type of termination does the connector have? This refers to how the wires are terminated in the connector housing. The most common type of “bayonet lock” would be a BNC connector commonly found on Oscilloscopes. Circular connectors can have a twisting locking feature known as “Bayonet Lock” or “threaded”. ![]() Most rectangular connectors will have a “latch” feature, such as a latch lock, locking ramp, etc. What is the fastening type? This would refer to a connector that would “latch” or “fasten” to its mate to hold them in place together to prevent accidental disconnection. Some circular connectors have the same shell size, but can have different orientations as well, so a photo really is best when determining this attribute. This one is a bit trickier to know or find, so a photo of the connector that shows the arrangement of the pins would be helpful if the shell size isn’t known. ![]() What is the Shell Size? This refers to circular connectors, and is what determines the layout of the pins. What is the row spacing? This is just like the pitch, but for the spacing between the rows from center to center. How many rows are there on the connector? This refers to rectangular connectors, and the amount of horizontal rows the connector has. There are other options as well, such as d shaped or terminal block connectors as well. What shape is the connector? The two most common types of connectors are circular or rectangular. Here are some other things to consider when Identifying a connector: If you have a connector or other Electronic component you need help identifying please Create a TechForum post along with your information right in the Part Identification Category. female sockets) and connection style (crimp, solder, pcb pin). If free hanging, advise the wire gauge used.Ĭontact information such as gender (male pins vs. Mounting Style - examples include Panel Mounted Through Hole / Surface Mount Vertical vs. Pitch - Try to be as precise as possible! Note the Number of positions (aka electrical connections) within the connector. ![]() Also good to note if you’re looking for the connector in the photo or if you’re in search of the mate. Include photos of the front and side of the connector. Pictures - An in-focus photo with measurements is worth a thousand words. But when you’re in a bind and need some extra help, the Digi-Key team is here for you. Tracking down a connector can be difficult.
