Q&A

Frequent Q&A

What are D-Sub connectors?

D-Sub connectors are named after their D-shaped form. They come in a variety of pin numbers to fit your computer application needs.

Are D-Sub and Serial Connectors the same?

Yes, they are the same thing.

What are the advantages of using a solder connector?

When using solder connectors, it is a more permanent solution as compared to crimp connectors. You do not have to worry about pins being pulled out on solder connectors which can happen in crimp connectors. For this reason, soldering can be more reliable.

What are the advantages of using a crimp connector?

Using crimp connectors is often just as reliable as solder connectors, but they take less time to install. Installation is as simple as squeezing a crimping tool to secure the connection.

What are the benefits of using a plastic metalized plastic or metal hood for my connector?

Plastic hoods are the most economical option when constructing D-Sub connectors. Metalized plastic hoods provide shielding against EMI/RFI interference while still being an economical option. Metal hoods provide durability as well as shielding against EMI/RFI interference.

What all do I need to assemble a DB25 Connector?

You only need a few things to make a DB25 Connector. There are two types you can choose from; solder type or crimp type.

Solder Type: To make a solder type connector you will need either a male or female solder type connector, a DB25 hood (metal or plastic depending on your preference), a DB25 grommet, and a soldering iron.

Crimp Type: To make a crimp type connector you will need either a male or female crimp type connector, D-Sub crimp pins to match the gender of your connector, a DB25 hood (metal or plastic depending on your preference), a DB25 grommet, and a D-Sub crimp tool.
