The SENSEI by Steelseries uses a Laser sensor from Avago, specifically the ADNS-A9500, providing a DPI/CPI range of 1 to 5,700 CPI. This is combined with a 32 bit ARM. This results in a tracking speed of 150ips, and a maximum acceleration of 30G. It uses a USB connection with a 2m, braided cable. The SENSEI is considered to be an ambidextrous mouse. It weighs in at 102 grams with the cable and is approximately 125.5 x 68.3 x 38.7 mm (LxWxH).
The Sensei is our version of the grand-master in our dojo. The name fits because everything we ever learned and researched about mice, all that makes a mouse great, is exactly what we built the SteelSeries Sensei around. It is one of those rare hardware products forged by love and science, trial and error, passion from professional gamers and a desire to push the envelope. SteelSeries Sensei was born for tournament victory; it was built to help you win. Master your game. Meet the Sensei.
SteelSeries Sensei can be fast, like really light-speed fast, if you need that kind of speed. Because we use a 32-bit ARM processor in the mouse, we can double (x2) your mouse sensitivity. The default CPI ranges from 1 to 5,700. Doubling that allows for 5,701 to 11,400.
The ARM processor is as fast as the original 75MHz Pentium processor. That may sound like overkill, but it;s this type of power that allows us to do sophisticated calculations directly on the mouse without the need for software drivers and without having to rely on the user's computer.
