Product type
D-Sub connectors, short for D-subminiature connectors, are a type of electrical connector used for a variety of applications in electronic devices. They are characterized by their D-shaped metal shell which provides mechanical support and ensures proper alignment. Typically made from materials such as plastic and metal, these connectors come in various pin configurations and sizes to accommodate different electrical requirements.
| Material | Plastic housing with metal shell |
| Pin count | 9 to 37 pins |
| Contact plating | Gold or nickel plating |
| Current rating | Up to 5A per contact |
| Voltage rating | Up to 250V |
| Temperature range | -55°C to +125°C |
When selecting D-Sub connectors, consider the number of pins required for your application and the current and voltage ratings needed. It's important to specify the contact plating material for durability and conductivity, as well as the temperature range suitable for your operating environment. Additionally, check for any required certifications or standards that may apply to your specific industry or application.
