Razer Tartarus pro Gaming Keypad: analog optical gaming keypad
*OPEN BOX* *SHOWROOM CONDITION* Analog Optical Switches Instead of traditional digital key presses that are simply pressed/unpressed, the Tartarus Pro uses Razer Analog Optical Switches. These switches measure how far each key is pressed, using an infrared light beam and sensor to detect displacement. This enables true analog input — meaning a key can output a range of values between 0% and 100% instead of just off/on. You can adjust how far a key must be pressed before it registers (e.g., from about 1.5 mm to 3.6 mm), which lets you tune responsiveness for your play style The keypad includes 32 fully customizable keys that can be remapped, macro‑assigned, or set up with dual functions. Per‑key Razer Chroma RGB lighting lets you customize color effects and sync lighting with other Razer Chroma devices.
