Premium 5-Pin Circular Magnetic Pogo Pin Custom Solutions
CTP’s 5 pin circular magnetic pogo pin module provides a revolutionary, elegant connection solution tailored for lightweight, micro-sized smart wearables. Designed to perfectly match the sleek product IDs of smart rings and smartwatches, this circular connector ensures 360-degree visual appeal and a seamless blind-mating charging experience.
Anti-Rotation Design & Lightweight Wearable Optimization
Connecting micro-devices requires extreme precision and a delicate touch. That is exactly why our 5 pin circular magnetic pogo pin utilizes a unique circular housing integrated with a physical anti-rotation notch (fool-proof slot). This completely eliminates the risk of rotational short circuits during blind mating. Furthermore, to accommodate the extremely light weight of these devices, we have meticulously tuned the magnetic force to a golden ratio of 250g, paired with a gentle 60g single-pin spring force. This ensures a satisfying “click” upon attachment without the spring tension pushing the lightweight device away.
Despite its extremely compact footprint, this module safely handles a stable 1A rated current and 5V DC voltage, achieving an ultra-low contact resistance of < 30 mΩ for high-fidelity signal transmission and fast charging. Built for scenarios where the device touches the skin, the pins feature a premium 5μ” gold plating over a brass base, offering excellent conductivity, anti-oxidation, and anti-allergy properties. With an IP65 waterproof rating via precision in-mold injection, 48-hour salt spray testing, and a mechanical lifespan of 50,000 mating cycles, it provides unmatched durability against daily sweat and moisture.

Frequently Asked Questions (FAQ)
Why is this circular magnetic pogo pin ideal for smart rings and watches?
The unique circular housing perfectly matches the rounded designs of modern micro-wearables. Additionally, the physical anti-rotation notch ensures the 5 internal pins align perfectly every time, providing safe charging and data synchronization in a micro-space without the risk of short circuits.
Is the magnetic force suitable for very light devices?
Yes. We have specifically tuned the magnetic force to 250g and the spring force to a gentle 60g per pin. This optimal balance ensures a secure magnetic hold without the spring tension accidentally pushing the lightweight device away from the connector.
How durable is this connector against sweat and moisture?
Designed for close-to-body wearables, it features precision in-mold injection to achieve an IP65 waterproof rating, protecting against daily sweat and splashes. The 5μ” gold plating and successful 48-hour salt spray test ensure exceptional corrosion resistance and a long lifespan of 50,000 mating cycles.
