What Is a Rotary Encoder? Analysis of Applications and Selection for Domestic Rotary Encoders
I. What is a Rotary Encoder? A rotary encoder is a measuring device that converts mechanical rotational motion into electrical signal output. Primarily used to detect angular position, rotational speed, direction, and displacement changes, it stands as one of the most critical sensors in industrial automation systems. In practical industrial applications, rotary encoders are typically mounted on motor shafts, gearboxes, reels, turntables, or rotating mechanisms. By outputting pulse signals or digital position information, they provide precise feedback to PLCs, motion controllers, or higher-level systems. Based on output methods, rotary encoders are primarily categorized into: II. Role of Rotary Encoders in Industrial Systems In modern automated equipment, rotary encoders primarily fulfill the following critical functions: They serve as nearly indispensable fundamental components in fields such as CNC equipment, lifting machinery, metallurgical machinery, automated production lines, packaging equipment, and energy systems. III. Domestic...
