Magnetic Pogo Pin Connectors
Basic Magnetic Connector Structure
A magnetic connector is a spring-loaded electrical connector that uses permanent magnets to align and hold its two halves together, instead of a mechanical latch or friction fit. Pogo pins on one side press against flat contact pads on the other, so the magnets handle both self-alignment and a consistent contact force — and the joint separates safely if the cable is pulled. The diagram below shows the main components.
Common Materials for Magnetic Connectors
Barrel
- Beryllium Copper: Provides excellent spring properties and electrical conductivity for the barrel housing.
- Brass: A cost-effective option for lower-stress, lower-cycle applications.
Plunger
- Beryllium Copper: Provides excellent spring properties and electrical conductivity.
- Brass: Cost-effective option for lower-stress applications.
- Stainless Steel: Enhanced corrosion resistance for harsh environments.
Spring
- Stainless Steel: Enhanced corrosion resistance and consistent spring force in harsh environments.
- Carbon Steel: A cost-effective option offering reliable spring force for standard-duty applications.
Magnet
- Neodymium (NdFeB) N42: High pull force in a compact footprint, nickel-plated for corrosion resistance.
- Ferrite: Lower-cost, lower-force option for light-duty or cost-sensitive designs.
Magnetic Connector Key Specifications
Every Promax magnetic connector pairs spring-loaded pogo pins with an embedded magnet pair, so the mechanical hold and the electrical contact are engineered together — not bolted on as an afterthought.
Magnetic Force
Pull force is tuned per application — light enough for a one-hand wearable release, strong enough to hold a charging cradle steady under vibration. Custom magnet grades and diameters are available.
Polarity
Pin layouts and magnet orientation are keyed so the connector can only mate one way, preventing reverse-polarity damage during blind or one-handed docking.
Waterproof Rating
IP67/IP68-rated sealed variants are available for wearables, outdoor, and medical enclosures — see our waterproof magnetic connector range.

Assembly
The plunger, spring, barrel, and magnet are precisely assembled into a single magnetic connector, ready for electrical and mechanical testing.
Testing
Every batch undergoes comprehensive electrical and mechanical testing, including 100% contact resistance checks and mechanical force verification.

Application Scenarios of Magnetic Connectors
Magnetic pogo pin connectors are used wherever fast, fail-safe docking matters more than threaded screws or fragile USB shells. Their self-aligning pull-on/break-away behaviour, sealed waterproof variants, and 10,000+ mating cycles make them the default contact interface across nine major industries:
Consumer Electronics & Wearables
Smartwatches, fitness trackers, true wireless earbuds, AR/VR headsets, and tablet keyboards rely on 2-pin and 4-pin magnetic connectors for charging docks and accessory attachments. The magnetic break-away prevents device damage if a cable is yanked — a key reason laptop and earbud OEMs spec them over USB-C for charging.
Medical & Healthcare Devices
Continuous glucose monitors (CGMs), hearing aids, ECG patches, hospital infusion pumps, and surgical robotics use medical-grade waterproof magnetic connectors rated to IP67/IP68. Self-cleaning pin contacts and gold-plating tolerate repeated sterilisation cycles without electrical drift, satisfying ISO 13485 traceability requirements.
Electric Vehicles & E-Mobility
EV battery management systems, e-bike charging cradles, dashboard cameras, and in-vehicle accessory mounts use high-current magnetic connectors carrying up to 15A. The blind-mate alignment is critical for drivers connecting in dark or gloved conditions, and the low contact resistance (~30 mOhms) minimises heat under sustained load.
Industrial Automation & Robotics
End-of-arm tooling, AGV/AMR charging stations, modular factory sensors, and quick-change robotic grippers depend on multi-pin magnetic connectors for tool-changing without operator intervention. Their high cycle life supports 24/7 production-line duty cycles where threaded connectors would loosen.
IoT, Smart Home & Security
Smart locks, robotic vacuums, video doorbells, and modular smart-lighting systems use compact 1-pin and 3-pin magnetic connectors for charging cradles and signal lines. The contact-only sealed design is moisture-resistant for outdoor enclosures.
Aerospace, Defence & Military Equipment
Drone docking stations, satellite communication modules, soldier-worn devices, helmet-mounted displays, and field radios benefit from rugged magnetic mating that withstands shock, vibration, and rapid field swaps. Vacuum-compatible plating options support extra-atmospheric deployments.
Outdoor & Rugged Portable Devices
Two-way radios, dive computers, body-worn cameras, GPS handhelds, and ruggedised tablets use sealed magnetic connectors to survive immersion, dust, and drop impacts that would destroy a USB port.
Education, Toys & Modular Robotics
STEM kits, programmable robots, and magnetic-tile electronic toys use multi pin custom magnetic connectors so children can snap modules together without exposed contacts or polarity errors.
