Product Introduction

Dongguan Xinteng Electronics Co., Ltd. is one of the most reliable manufacturers and suppliers of magnetic pogo pin connector for wearable devices in China, featured by quality products and good service. Welcome to wholesale bulk durable magnetic pogo pin connector for wearable devices in stock here from our factory. Also, customized service and OEM&ODM service are available.

Magnetic pogo pin connector for wearable devices

This ultra-compact magnetic connector offers the following advantages:
1. Ultra-thin female magnetic connector available in multiple sizes, with heights of 1.5mm and 2.0mm available.
2. Waterproof to IP67.
3. Corrosion and oxidation resistant, with a 96-hour salt spray rating.
4. Space-saving, compact size, Ø4.5mm.
5. Suitable for smart rings, smart cards, locators, card readers, and other small electronic products.

Note: If your factory is in mainland China, you can send the magnetic connector female to our company after the SNT is completed. We can assist in magnetizing the magnetic connector female free of charge. If your factory is outside of mainland China, you will need to find a local magnet factory to magnetize the magnetic connector female.

Product Usage Notes

Precautions for using magnetic Pogo pin connectors for wearable devices: Due to their small size, female magnetic connectors cannot be hand-soldered and must be soldered using surface mount technology (SMT). Therefore, female magnetic connectors are shipped without magnets. They undergo 100% inspection before shipment and are shipped in tape and reel packaging.

Note: You need to SMT the female connector onto the PCB board, and then hand over the entire PCB with the female connector to the magnet factory. The magnet factory will magnetize the female magnetic connector to make it have magnetic adsorption force so that it can be used with the male magnetic connector for charging.

Application examples of magnetic pogo pins

Our Magnetic Pogo Pin Connector for Wearable Devices is currently the most common device used in smart rings. Because smart rings have extremely limited internal space, housing batteries, sensors, and control chips, there's virtually no spare space. Traditional thick sockets simply won't fit. This is why our 1.5mm ultra-thin female magnetic connector is so crucial. Not only is this connector compact, it also fits naturally with the curved surface of the ring, eliminating any protrusions that might interfere with the wearer's experience. This allows the ring to appear like a piece of jewelry on the hand, without any unwanted protrusions or discomfort.

Next, let's discuss how to install the female connector on a smart ring. First, a retaining groove is created on the ring's inner wall, deep enough to accommodate a 4.5mm diameter female Pogo Pin connector. After the female magnetic connector has completed the SNT process, it can be sent to a magnet manufacturer for magnetization. After magnetization, it can then be mounted. Mounting is typically done by reflow soldering or adhesive dispensing to secure the female connector securely to the circuit board, which is then bonded to the ring housing.

FAQ

Q: What is magnetization?

A: Magnets aren't inherently magnetic. When they're first made, they're mostly non-magnetic, like an ordinary piece of iron-nothing special about them. To make a magnet magnetic, it needs to go through a magnetization process. Magnetization uses a strong magnetic field to align the "magnetic domains" within the magnet. Before magnetization, the magnets are randomly oriented, resulting in no apparent magnetism. Once exposed to the strong magnetic field of a magnetizer, the magnets align in the same direction, becoming truly magnetic.

Q: What equipment can this small surface-mount magnetic connector be used in?

A: It can be applied to smart rings, smart cards, locators, card readers, smart underwear in the health field and other small electronic products and wearable products.

Q: Can it be applied to card readers and locator devices?

A: Yes, card readers and locators share a common characteristic: their small size. The card readers we commonly encounter, whether used in banks, subway turnstiles, or company access control systems, all share a common characteristic: frequent plugging and unplugging and repeated use. In such high-frequency operation, the biggest advantage of magnetic connectors is their "auto-alignment." They rely on magnetic attraction, eliminating the need for users to carefully align the connector.

Q: Will the magnetic force of the magnetic interface interfere with the sensors in the device?

A:No, because the magnets used in magnetic connectors are typically small rare-earth magnets with a limited magnetic force range. Their primary function is to securely hold the male connector in place. Their magnetic field isn't strong enough to penetrate the device's shielding, let alone affect common components like gyroscopes, accelerometers, and heart rate sensors. During design, our engineers intentionally stagger the magnets away from sensitive components, even adding a layer of shielding material to "isolate" them, ensuring that the magnetic force is solely used for alignment.

Q: Can this product be used on smart cards? If so, how do I install it on a smart card?

A: For use on smart cards, a female connector approximately 2mm thick can be purchased and inserted directly into the edge of one side of the card. During installation, a small opening is reserved in the card casing to insert the magnetic connector. It is then secured flush with the card surface using ultrasonic welding or glue. This ensures that the overall thickness of the card is maintained, while also minimizing the feel. Because the card itself is relatively thin, the connector also requires a thin structure.
