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. -
