Delve into the realm of rotary encoders, known by various monikers like shaft encoders. These electro-mechanical marvels specialize in translating the angular orientation or movement of a shaft or axle into analog or digital output signals. An incremental rotary encoder serves as a proficient tool for quantifying distance, velocity, and positioning. Rotary encoders find their application across a diverse spectrum of scenarios where the surveillance or regulation, or even both, of mechanical systems stands paramount. Their usage spans industrial controls, robotics, optical equipment like camera lenses, human-computer interfaces such as optomechanical mice and trackballs, precision rheometers, and rotating radar platforms.
