Discover Our High-Quality Plug Connectors
A connector is an electromechanical device that establishes an electrical connection between two electronic components. This ensures that performance is not compromised and signals are transmitted reliably. Connectors are essential across a wide range of industries and for the manufacture of countless products.
The majority of connectors can be divided into two categories: male and female connectors. The male part is also known as the ‘pin’ or ‘plug’ and is connected to the female energised part. The female part of a connector is called a ‘coupling’ if it is the end of a cable. The term ‘socket’ is also used if it is an integral part of an electronic device. For non-compatible connectors, an adapter is used to enable the connection. To create a permanent connection, the connector can be permanently installed. It is also possible to install and remove the connection as required. This is referred to as a detachable or separable connection.
Depending on the area of application, different requirements are placed on connectors. Depending on the type of signals that need to be transmitted, the electrical connections have to fulfil very specific requirements. In particular, the current and the voltage level are of decisive importance when selecting a suitable connector. The IP protection classes, which include the provisions for protection against foreign bodies, contact and water, also play an important role.
Eine Vielzahl unterschiedlicher Plug Connector wird in den unterschiedlichsten Branchen und für die Herstellung unzähliger Produkte benötigt. Besonders hervorzuheben sind die Bereiche Industrieelektronik, Plant and mechanical engineering, Automation, Automotive und Electrical engineering. Aber auch in den Sparten Energie- und Air conditioning technology, Medical technology, Transport- und Verkehr ist der lösungsorientierte Einsatz von Steckverbindern von Bedeutung.
To meet the various requirements, different electrical connection technologies are used in the field of connectors. These include:
- Printed circuit board connection technology
- Soldering technology
- Welding technology
- Press-fit technology
- Crimping technology
- Insulation displacement technology
- Overmoulding

We Cover All Standards in the Field of Plug Connections!
Standards in the Field of Plug Connections! A large number of differently standardized connectors are used worldwide. These include standards for the geometric shapes of plugs, sockets, couplings, and connectors, as well as for the electrical or optical signals transmitted via cables or fiber optic cables. There are many different connector types and designs, such as DIN 41 612, DIN 617, DIN circular connectors, HDMI, and M5/M23 miniature circular connectors.
