1. Classification of D-SUB connectors
Solder cup D-Sub connector: This connector meets commercial industrial standards and can be paired with any docking solder cup D-Sub connector. The contacts are electroplated with flash gold, and the connector insulator meets the UL94V-0 standard. The maximum wire size is 20 AWG, and 9, 25, 37 and 50 pin specifications are available.
Crimp D-Sub connector: Crimp D-Sub connectors meet commercial industrial standards and can be used for most standard D-Sub male connectors. Compatible with 20-28 AWG wire range, available in 9, 15, 25 and 50 pin sizes.
Punch-type D-Sub connector: This connector is easily soldered into the through-hole of the printed circuit board or used in many other applications. Solder placement follows a standard footprint, and gold-plated contacts ensure long life. As an industrial standard commercial DB37 female PCB type connector, it has standard mounting holes for application flexibility. -
2. Specifications and models of D-SUB connectors
There are many specifications and models of D-SUB connectors, and the common ones are D-SUB 9-pin, D-SUB 15-pin, D-SUB 25-pin and other series. These series have their own scope of application and characteristics. Users can choose the appropriate specifications and models according to actual needs. At the same time, the prices of different specifications and models are also different. Users need to consider factors such as cost and applicability when choosing.
