Rotary encoders are electronic measuring devices that measure the angle of rotation. There are two types of rotary encoders: absolute and incremental. Absolute encoders measure position in angular units, and each position of the encoder has a unique code value. Incremental encoders measure the angle of rotation by generating electrical pulses in response to each step of the encoder's rotation. Rotary encoders have applications in various industries, such as production of production lines, OEM machinery, CNC machines, stage automation systems, paper production, and wood processing. In production lines, rotary encoders are used to precisely position elements such as rollers, rollers, or throttles in the production process. Absolute encoders are particularly useful in production lines, where measurement repeatability and reliability, as well as precise control of machine movement, are required. In OEM machinery production, rotary encoders are used to control linear and rotational movement in various types of machines and equipment. These encoders are used in industrial robots, CNC machines, production lines, and other industrial machinery. Incremental encoders are particularly useful in CNC machines, where these encoders are used to quickly and accurately position tools in the machining process. In stage automation systems, rotary encoders are used to precisely control the movement of various devices such as reflectors, curtains, platforms, or scenes. Absolute encoders are used to precisely position devices, and incremental encoders are used to quickly read and control movement. In paper production, rotary encoders are used to control the movement of machines such as rollers, roles, and cutters. Absolute encoders enable precise control of machine movement, and incremental encoders are used to quickly read and control movement. In wood processing, rotary encoders are used to precisely position elements such as saws or drills in the wood processing process. Absolute encoders allow for precise control of machine movement, and incremental encoders are used to quickly read and control movement.
