Welcome to wholesale bulk durable circular magnetic connector in stock here from our factory. Also, customized service and OEM&ODM service are available.

The advantage of this magnetic Pogo Pin lies first in its connection method. The circular Pogo Pin connector design maintains an aesthetically pleasing appearance while maintaining stable contact pressure. It's compact and space-saving, yet durable and reliable, ensuring stable charging and signal transmission. With a diameter of 8.0mm, this circular magnetic connector is ideal for small wireless LED lights, action cameras, and video recorders. Its small size doesn't detract from the overall design, yet it maintains stable and reliable performance.

More importantly, the magnetic connector is user-friendly. When the device is placed near the charging dock or magnetic charging cable, the female connector has a 400g retention force, allowing the Pogo Pin to easily align, eliminating the need for careful angle adjustment for insertion and removal. This design provides substantial convenience for users. It also reduces the hassle of mass production and assembly for manufacturers, and the connector is durable and less susceptible to wear and oxidation.

The circular magnetic connector has an 8.0mm diameter, making it both compact and durable. The pogo pin, with a 1.0mm diameter, is large enough to provide ample current flow, capable of carrying a maximum current of approximately 3A. Its circular design also creates an aesthetically pleasing aesthetic, preventing connector issues from detracting from the device's overall simplicity.

• First, avoid full compression.

Every pogo pin has a total stroke and a working stroke. The total stroke only indicates the maximum it can physically be compressed. However, in actual applications, it's best to stick to the recommended stroke. For example, if the design specifications specify a 1.5mm total stroke, a recommended stroke of around 1.0mm is recommended. Using the recommended stroke ensures sufficient contact force without pushing the spring to its limit, which can accelerate the lifespan of the pogo pin, significantly extending its lifespan.

• Second, consider the stability of the spring force.

If the compression is too shallow during operation, the spring force will be insufficient, causing the contact point to loosen easily. Conversely, if the pogo pin is compressed too deeply during operation, the spring will be under high stress for a long time, quickly fatigued, or even deformed. Therefore, suppliers generally provide a rated spring force range, such as 60g ± 20g, which is just enough to ensure stable contact at the recommended stroke.

• Third, pay attention to product tolerances.

During actual assembly, there will be some tolerances in the pin height, housing thickness, and PCB position. If engineers leave only a narrow compression space during design, mass production may result in some products being compressed too deeply and others too shallow. Therefore, engineers must factor in tolerances and leave a safety margin when designing the compression stroke.

• Fourth, consider friction and wear.

Excessive compression stroke increases friction between the pogo pin and the test point. Over time, the plating can easily wear away, increasing resistance. This is especially true for test fixtures used for high-frequency plugging and unplugging. A reasonable stroke directly determines the frequency of maintenance.

• Finally, simulate real-world operating conditions during testing.

Many people assume the resistance is reliable after just a few compression tests in the lab. However, it's best to perform cyclic testing, simulating a realistic number of compression cycles, such as 10,000 or 20,000, to verify resistance fluctuations and elasticity. This provides a reliable result.
