Non-Contact Power Transmission Module

Seiko Epson announced a module enabling non-contact power transmission. The product is made up of a power transmission module (primary module: S4E16402) and a power receiving module (secondary module: SE16403). Using these two elements as a set enables transmission of up to 0.5 W (5 V/100 mA). The thin, flat coil used for power transmission results in a compact design, with the secondary module having an overall thickness of just 2.3 mm. Electromagnetic shielding fitted to the back of the transmission surface in each module reduces interference with other electronic components contained within the same device. The module enables customers to incorporate advanced safety measures for noncontact power transmission into their designs, with built-in safety features including metal detection, secondary detection and automatic cut-off in the event of excess current or abnormal temperature. The 0.5 W output unit outlined above is the first in an array of module products of varying output levels that Epson plans to produce using its newly-developed non-contact power transmission technology, enabling the company to continue meeting diverse customer needs.
