The selection of d-sub high density connectors wholesale must first think about the application environment, whether it is used indoors or outdoors, whether it is used in a corrosive environment, because it will affect whether it is necessary to enhance its sealing or cover the shell outside the insulator. It also determines which terminals to use and how many conductive terminals to organize.
When purchasing d-sub high density connectors wholesale, you should also consider the environmental requirements and expected orientation, because its location determines the temperature, humidity and other environmental conditions. Also think about the storage environment, think about the impact and sensation of the request including shipping requests and production environmental conditions, especially the production environmental conditions to think about, such as welding temperature and welding cycle duration requests.
Then I think about the electrical requirements of d-sub high density connectors wholesale. The electrical requirements mainly consider whether the voltage and current requirements can be well used in such electrical requirements. Also need to think about the change of resistance, millivolt drop, larger current value, larger voltage value, influx current value, characteristic impedance, plug loss cover power and so on.
The mechanical properties of d-sub high density connectors wholesale determine the mechanical properties used in all kinds of electronic and electrical equipment. When purchasing, we should think about how much volume and coverage area is useful, how much size service can be allowed, how much terminal piercing and pulling power is, and how durable. If it is used in a printed circuit board, it is also necessary to determine the public service of the circuit board, because it is the critical value of the aviation connector and the feasibility of reaching the critical value. If it is used for low-power circuits, it is also necessary to understand whether the coating and the underlying data are specified and the signal specification and environmental grade are common.
d-sub high density connectors wholesale has a variety of standards, but the manufacturer chooses about 25 test organizations as the origin of all or some test standards for aviation connectors, and also considers the selection of appropriate test standards in specific use cases, these standards include universal standards. When choosing, you usually only need to choose according to your own needs.
