Precise electrical contact and high-density layout

The pogo pin's pointed tip allows for more precise positioning of tiny test points or pads. Because the pogo pin's contact area is smaller, it reduces distributed capacitance and inductance, improving high-frequency signal transmission efficiency.

Spring-Loaded Contacts High Current

The gold-plated pogo pin tip reduces contact resistance, allowing this product to transmit a high current of 5A.

Vibration-Resistant

Because the spring absorbs mechanical shock, it offers a certain degree of vibration resistance.

Environmentally Friendly Materials and Coatings

The spring pogo pin's tip, barrel, spring, insulating bead, and surface plating are all made from environmentally friendly materials that meet international standards.

Spring Loaded Contacts High Current Structure

To ensure more stable and precise contact, a pointed needle is used, and a steel ball or insulating bead is added to the needle barrel to reduce the current flowing through the spring. The steel ball inside the pogo pin provides more stable contact, resulting in better electrical performance. This offers the advantages of high current flow, low contact resistance, and stable performance.

Precautions For Using Pogo Pin

During the design process, the engineering drawings will clearly indicate the reasonable compression range. It must be used within this range. Excessive pressure will damage the tube opening, potentially causing pin jamming. Insufficient pressure will result in inadequate compression, leading to unstable impedance.
During assembly, special care must be taken to avoid impacts to the tube opening, as these can deform the opening and also cause pin jamming or poor contact.
Additionally, the battery contacts or FPC gold fingers mating with the Pogo Pin must be kept clean and free of any dirt or oxidation.

FAQ

Q: Why do some devices use pointed pogo pins instead of round ones?

A: The contact force advantage is due to the fact that pointed tips can more easily penetrate the surface oxide film or thin dirt upon initial contact, ensuring instantaneous conduction. However, pointed tips are more stable in applications where alignment is critical and the contact area is small, such as in test fixtures or where blind insertion is required. Furthermore, pointed tips provide positioning, providing a subtle "snap" and mechanical positioning when plugged in. They also offer better vibration resistance than round tips with the same mechanical parameters.

Q: Will pointed pogo pins scratch the contact surfaces?

A: There is a risk, but scratches are not guaranteed. By carefully considering factors such as the pogo pin tip angle/radius, spring force, mating surface coating/hardness, and the presence of lateral friction, and through careful design, the risk of scratches can be significantly reduced or eliminated.

Q: Can the Pogo pins be customized?

A: Of course. The shape, size, current, voltage, contact force, and more can all be customized.

Q: Does the pointed tip design affect contact impedance?

A: Yes, and the impact is both positive and negative. Pointed pogo pins are more likely to penetrate surface contamination like oxide layers or stains. Therefore, when the surface of a pogo pin is contaminated, it achieves lower instantaneous contact impedance than rounded tips.

Q: Is this high-current spring-loaded contact more prone to sparking?

A: Because the pointed contacts have a small contact area and high current density, arcing is more likely to occur if there's an air gap or a sudden current surge at the moment of contact. However, with our 5A current contact, we can mitigate the sudden surge by designing a pre-charge/delayed power-up circuit or incorporating a current limiter/soft-start circuit.
