Description

Overview

A magnetic charging connector with a 4.0 mm pogo-pin head and two contact pads. The male head mates with a female seat that solders to a board, so a wearable charges by touch instead of a plug.

Specifications

  • Connector: magnetic pogo pin, 2-pin contact pad
  • Head diameter: 4.0 mm
  • Genders: male cable end, female PCB seat
  • Termination: solder pads on the seat
  • Variants: USB lead, female seat, USB + Female pair

Purpose

Wearables have no room for a sealed USB port and their tiny inlets wear out. A two-pad magnetic face lines itself up and pulls free when the cable is snagged.

Applications

  • Watch and fitness band contacts
  • Water-resistant wearable builds
  • Repair and prototype boards
  • Wearable test fixtures
  • Desk stand charging pucks

How to Use

  1. Confirm the 4.0 mm head will seat against the watch body.
  2. Reflow each seat pad onto the board’s charge contacts.
  3. Check continuity and note which pad is positive.
  4. Bring the head to the seat and let the magnet align it.
  5. Caution: 5V only. A two-pad contact has no keying, so verify polarity before the first charge.
