What are Magnetic Toothbrush Pogo Pins?

what are magnetic toothbrush pogo pins

Magnetic charging toothbrush connectors use spring-loaded pins with neodymium magnet technology for self-aligning, waterproof charging. The spring mechanism (plunger design) inside each brass pin maintains electrical contact through compression and vibration. Magnets pull connectors together and automatically align them.

Two main configurations we manufacture:

Base Contact Charging

Your toothbrush sits on a charging base. Spring probes in the base connect with solid contact pads on the toothbrush handle. Neodymium magnets embedded around the pins hold the toothbrush in position through magnetic force. This electric toothbrush magnetic charger design provides direct electrical connection for efficient power supply.

Magnetic Charging Cables

A magnetic charging cable snaps onto contact points on your device. The cable end has pogo pin products that automatically align through magnetic alignment. Popular for travel electric toothbrushes, where you can use any standard charger.

The key advantage over wireless charging is efficiency, spring-loaded pin contacts transfer power with less heat. Unlike Type-C connectors, waterproof magnetic pogo pin designs have no opening where water enters, perfect for devices rinsed under running water.

How does Promax Manufacture Pogo Pin Connectors?

Precision Pin Manufacturing

Promax uses both precision stamping and CNC machining, depending on volume and complexity. High-speed stamping produces probe pins for volume orders (50K+ units) with ±0.01 mm tolerances for adaptability. CNC machining handles custom geometries and prototype quantities. Coordinate measuring machines (CMM) verify every dimension before plating.

Multi-Stage Electroplating and Plating Process

Our electroplating line deposits protective layers in controlled sequences:

  1. Alkaline cleaning removes machining oils
  2. Nickel strike plating (1.5-3.0 microns) creates corrosion barrier
  3. Gold flash plating (0.3-0.5 microns) ensures low contact resistance
  4. X-ray fluorescence (XRF) validates plating thickness on every production batch

SMT compatibility: Surface mount technology versions available with solder tail terminations for direct PCB pogo mounting.

Magnet Integration and Mating Assembly

Automated placement systems install neodymium magnets with consistent field orientation for magnetic connection. Pull force testing validates 200-500 gram specifications. Two-shot injection molding creates waterproof seals without gaskets. Ultrasonic welding joins housing components into hermetic enclosures, ensuring frequent connections without degradation.

Quality Testing Protocol

  • 100% electrical testing: Contact resistance measurement on every unit ensures electrical contact integrity
  • IP67 submersion testing: Sample lots tested at 1-meter depth for 60 minutes
  • Cycle life endurance: Sample testing to 50,000+ insertion cycles
  • Pogo test procedures: Salt spray testing per ASTM B117, pull force validation, high-speed cycling

Magnetic Toothbrush Pogo Pin FAQs

How do you prevent magnetic interference with toothbrush electronics?

Neodymium magnets in our pogo pin magnetic connector designs generate 200-500 gauss field strength at the contact surface. This field drops rapidly with distance following inverse square law, becoming negligible beyond 10 mm from the connector. We can simulate magnetic field distribution during design consultation if your toothbrush contains sensitive Hall effect sensors near the charging area. Standard brushless DC motors, lithium battery management circuits, and Bluetooth radios operate without interference from these magnet strengths.

Can you manufacture waterproof connectors for other personal care devices?

Yes. We manufacture waterproof magnetic pogo pin assemblies for electric razors, facial cleansing brushes, water flossers, hair trimmers, and epilators—any personal care device requiring waterproof charging in bathroom environments. Our IP67-rated assemblies withstand direct water spray during device rinsing. PEEK housing material options provide chemical resistance for devices exposed to cleaning solutions. Medical-grade designs meet biocompatibility requirements for devices contacting skin, and automotive-grade connectors handle vibration and temperature extremes.

What happens if connectors fail during the warranty period?

Promax guarantees all pogo pin magnetic products meet specified electrical and mechanical performance for 50,000 cycles minimum when operated within rated conditions (correct voltage, current rating, temperature range). Products failing to meet guaranteed specifications receive free remake or full refund, plus root cause investigation to prevent recurrence. We maintain design files for 10+ years, ensuring reorder availability throughout your product lifecycle. Field failure rate averages below 0.5% for connectors used within specifications, demonstrating our commitment as a reliable types of pogo pin manufacturer.
