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 closely 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 closely matches the rounded designs of modern micro-wearables. Additionally, the physical anti-rotation notch ensures the 5 internal pins align closely 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.
Engineering Review for 5 Pin Circular Magnetic Pogo Pin Module | CTP Custom Solution
This product page presents a CTP magnetic connector configuration for engineering reference. Final dimensions, electrical ratings, materials, magnet structure, sealing level and reliability targets are not universal values; they are confirmed against the approved drawing, installation condition and model-specific validation plan.
Information to provide for evaluation
- pin count, pitch, pin map and mating direction
- housing envelope, mounting method and device-side interface
- current, voltage, signal and contact-resistance targets
- magnetic retention, polarity, sealing, materials and finish
- sample quantity, validation plan and forecast volume
How specifications are confirmed
CTP reviews the application and prepares a drawing or specification for approval before sample production. Test scope, acceptance criteria and report format should identify the model, sample status, method, conditions, result and review date.
Can this magnetic connector be customized?
Yes. Customization can cover geometry, contact layout, materials, cable construction, magnetic structure, sealing and appearance. Feasibility depends on the application and approved specification.
Are the electrical and waterproof values universal?
No. Current, voltage, resistance, temperature rise and ingress-protection claims apply only to the identified model and stated test conditions.
What determines sample and production timing?
Timing is confirmed after the drawing, materials, tooling, sample quantity, validation scope and production requirements have been reviewed.
