Pin & Socket
Contact Technologies
Five proven connection technologies.
One commitment to performance.


1. Crimped
Crimped contacts are used to terminate multistrand wires, ensuring reliable and secure connections. The process involves pressing the wires into the contact, which can take the form of a pin or socket depending on the application.

2. Press-fit
A popular method, which may include additional pin features based on tolerances, achieves a snug fit by leveraging material properties. For instance, a press-fit is suitable for plastic assemblies when a client needs a connector.

3. Staked
Staking is a mechanical technique used to hit the pin from one end. It is commonly used for metal, ceramic, and plastic materials. This versatile approach comes in various forms: petal (for lamp bases), flatted (rivet-like), or control (for double-sided male pins). These options cater to different industry needs, ensuring optimal functionality and precision.
The Slimline Bulb Pin is a great example of our Staked Pins. If you’d like to see an example of the slimline pin – click here.
4. Soldered
A less common approach for hollow pins, but can be used for larger diameter pins when the application is taking advantage of the low overall weight of a hollow pin.
5. Overmolded
Another infrequent approach for hollow pins occurs when the pin is encompassed within a molding material, ensuring stability and security.
