What is a Pogo Pin? Introduction of Pogo Pin Connectors
1. What is the principle of the Pogo Pin?
The Pogo Pin is an electronic component mainly used as a test probe and connector. Its internal structure consists of a plunger, a spring, and a pin barrel. The principle is that when the Pogo Pin is connected, the plunger is pressed down by force, touching the wall of the pin barrel, allowing the current to be conducted through the two contact points.

2. What are the applications of the Pogo Pin?
The functions of the Pogo Pin include charging, mechanical fixation, internal antenna contacts, battery contacts, data transmission, board-to-board connections, etc. Compared to general connectors, it has a wider range of applications. Pogo Pins are often used in the charging bases of smart speakers and True Wireless Stereo (TWS) earbuds.

3. What types of Pogo Pins are there?
Based on structure and application, there are several types:
- Single-pin to multi-pin: Ranging from one pin up to 18 pins, etc.
- Ball-type Pogo Pin: Paired with a ball allowing the Pogo Pin to slide 360 degrees on a rail, suitable for electronic devices requiring movement, such as rotating monitors and surveillance camera lenses.
- Magnetic Pogo Pin: Pogo pins paired with magnets, typically with male and female ends. With the magnetic attraction design, they offer easier operation and a more stable connection.
- Waterproof Pogo Pin: Pogo pins sealed for waterproofing based on requirements. (Insert molding, sealing or O-ring)
- High-current Pogo Pin: Designed specifically to carry high current (we also offer crown connectors that can withstand up to 600 amps; please inquire online).
- Ultra-small Pogo Pin: With a pin length of only 1mm, suitable for portable devices and consumer electronics requiring miniaturization.

4. What are the advantages of the Pogo Pin?
The main advantages of the Pogo Pin include:
- Compared to standard connectors, Pogo Pins can be fully customized from the housing to the pin, offering high application flexibility.
- Produced through high-precision metal turning machines, Pogo Pins do not require molds, allowing for shorter development, sampling, and production times, reducing costs.
- Longer service life compared to other connectors, reducing mechanical wear on components.
- With the miniaturization trend in electronics, Pogo Pins offer a better space-current ratio than standard connectors, maximizing transmission efficiency in minimal space.
- Easy to connect, unlike standard connectors which can sometimes be hard to plug and unplug. Especially magnetic connectors, which simply attach magnetically, offering an excellent user experience.
In conclusion, Pogo Pins are relatively stable and reliable products. If you wish to save space efficiently and have higher customization requirements, then pogo pin connectors are the most efficient alternative.
