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