Sanwa Supply introduced the MA-NANOIR13 series wireless optical mice, which feature infrared optical sensors. The infrared sensors draw lesser power than visible light sensors, and hence conserve battery. The sensors offer tracking resolution as high as 3000 DPI, this resolution can be switched on-the-fly between 3000, 1500, and 1000 DPI. Oriented for the right-hand, the MA-NANOIR13 has two side buttons apart from its three main buttons and a 2-way scroll-wheel.

Measuring 55 x 107 x 36 mm (WxDxH), these mice weigh 70 g without batteries, they take in two AA-size ones. With a pair of mainstream alkaline batteries, up to 15 months' battery-life can be expected. The mouse talks to the host machine over 2.4 GHz radio band, a USB micro-receiver is included. The MA-NANOIR13 comes in three color options, black, silver, and red. They are priced at 3,675 JPY (US $44.6).
