Pogo pins are a type of electrical connector that is widely used. Their small size and cylindrical shape distinguish them. Pogo pins are typically 1 to 10 millimeters in diameter and 2 to 25 millimeters in length. Pin ends are typically flat but can also be tapered or beveled. Pogo pins are frequently used in situations where space is limited and dustproof and waterproof requirements exist. They are also used when two circuit boards must be connected without a physical connector.

Materials

Pogo pins are made from various materials, including brass, SUS304, 316F, 316L, CuTe, HBi59, and CuSn; the intended application and the level of durability required determine the material used.

Coating and plating

Pogo pins can be plated with various materials, including Au, Ag, Pd, Pt, Rh, Ru, Ni, and others. Plating is commonly used to improve electrical conductivity or to provide corrosion resistance.

Coating: Various materials, such as silicone or Teflon, can be used to coat the spring. Coatings are typically applied to pogo pins to increase their durability or to provide resistance to a specific environment.

Pogo pin type

The following are the most common types of pogo pins:

SMD/SMT Pogo Pin

Through Hole Pogo Pin

Double-Ended Pogo Pin

High Current Pogo Pin

Right Angle Pogo Pin

Bending Type Pogo Pin

Solder Cup Pogo Pin

Thread Screw Pogo Pin

SMT/SMD pogo pins: Similar to standard pogo pins, SMT (surface-mount technology) and SMD (surface-mount device) pogo pins have a smaller body that can be mounted directly onto a PCB.
