What Are Connectors?

Connectors (steckverbinder in German) are the bridge between electrical circuits. Without them, circuits wouldn’t be able to do their job. While connectors vary widely in type and application, they all do one thing: they join together circuits. Modular connectors are designed based on function (not the other way around) and different components can be added to change the ease of connection, mating, durability, and more.  In some cases, connectors must be made to withstand the toughest and most extreme conditions on the planet.

Types of connectors include (but are not limited to):


  • Blind Mate Connectors
  • D-Sub Connectors
  • Hot Swap Connectors
  • IP67 Connectors
  • Military Connectors
  • Modular Connectors
  • Power Connectors
  • Press-Fit Connectors
  • Space Connectors

As you might expect, male connectors have pins that protrude out, while female connectors have sockets. When you bring them together, they “mate” to form the connection. Keying is something you can do to ensure that the connection is made well.

Connectors are used in a variety of applications – ranging from military use to space travel to medical and consumer electronics. Regardless of how they are used, they secure a connection between circuits and create a bridge to allow the circuits to complete their purpose.

They come in many shapes and sizes. Although most connector manufacturers give catalogs of products, you can also ask a connector to be custom-designed to match nearly any need that you might have.
