Shop D-subminiature connectors and accessories for computer, communications, instrumentation, control and industrial electronic applications. Wallco offers DB9, DB15, DB25 and other D-sub configurations along with backshells, hoods, adapters and mounting hardware.
Compare products by contact count, shell size, connector gender, density, termination style and mounting configuration.
D-sub connectors are multi-contact electrical connectors commonly used in computers, communications equipment, instrumentation, industrial controls and electronic devices. The characteristic metal shell provides mechanical alignment and can also provide shielding when used with an appropriate connector assembly.
D-sub connector families include several shell sizes and contact arrangements. Common applications use 9-, 15-, 25-, 37- and other contact configurations, as well as high-density versions that place additional contacts within a similar shell size.
Always verify the actual contact count rather than relying only on the common DB-style name used for the connector.
D-sub connectors are available in plug and receptacle configurations. Connector gender should be verified along with the mating equipment before ordering.
Depending on the connector design, D-sub products may use solder-cup contacts, crimp contacts, insulation-displacement termination or direct PCB mounting. The appropriate termination method depends on the cable, board design and assembly process.
Standard-density and high-density D-sub connectors use different contact arrangements. Products with similar external shell dimensions may not be electrically or mechanically interchangeable.
Backshells and hoods provide mechanical protection, cable strain relief and, in some designs, shielding around the terminated connector. Select the backshell according to connector shell size, cable diameter and cable-entry direction.
D-sub adapters and gender changers can change the physical interface between compatible connectors. These products generally do not convert the underlying electrical signal or communications protocol.
Screw locks, jack screws, thumbscrews and related hardware help secure mating D-sub connectors. Thread type and hardware dimensions should be matched to the connector and equipment panel.
