Beauty devices usually need two or four contacts. Two pins supply power; four pins add identification, temperature feedback or in-place detection, which lets the device recognise the accessory and control charging safely.
Because these products are used with wet hands and cleaned often, plating thickness and sealing matter more than in dry environments. We recommend gold plating matched to the cleaning cycle and a contact layout that sheds water instead of trapping it.
Share the housing curvature, available space and charging current, and we will match the magnet direction, contact layout and sealing concept to your enclosure.
