Structure

Components

You find that SMT Pogo pins have a simple but clever structure. Each pin contains three main parts. You see a plunger, a barrel, and a spring. These parts work together to create a reliable connection.

Here is a table showing the typical materials used for each component and their key properties:

You notice that manufacturers choose materials based on the needs of your device. For example, beryllium copper gives you strong and reliable performance, especially in high-frequency circuits. Brass helps you save costs, but it may not last as long under heavy use. Stainless steel springs resist corrosion, so you can use them in harsh environments.

Tip: You should check the material of each component before you select a pogo pin for your project. The right choice helps you get better durability and performance.

Spring mechanism

You rely on the spring mechanism to keep your electrical connections stable. The spring sits inside the barrel and pushes the plunger outward. This action creates a constant force, which keeps the plunger touching the contact pad on your circuit board.

The spring does more than just push. It stores energy in its tightly wound coil. When you press the pogo pin onto a pad, the spring compresses and then bounces back. This bounce helps overcome small bumps or rough spots on the surface. You get a steady connection, even if your device shakes or moves.

Here is a table that explains how the spring mechanism works:

You can choose springs with different force levels. Most SMT Pogo pins use a force of about 60 grams at mid-stroke. Some pins offer 50 gf, 80 gf, or even 100 gf. You select the force based on how much pressure your application needs.

Typical force at mid-stroke: 60 grams

Available forces: 50 gf, 80 gf, 100 gf

You see that the spring mechanism is the key to making SMT Pogo pins work well in many devices. It helps you get a reliable connection every time, even in tough conditions.

Function

Electrical contact
