Key Trends Shaping the Market:
Several electromechanical devices can operate on a light source, photo sensors or photosensitive detectors. Upon integration with an optical grating system to convert linear or rotary position to an electrical signal, it is known as an optical encoder. It is a transducer that is widely used for measuring rotational motion.
Optical encoders detect optical pulse signals, convert them into electrical signals, and then provide outputs. They are easier and ideal to improve accuracy and resolution than magnetic encoders.
Optical encoders are motion sensing devices that can be used in applications where a strong magnetic field is generated. They translate linear or rotary motion into a digital signal that is then sent to a controller. The controller uses this signal to monitor motion parameters such as speed, distance, direction, rate, or motion.
Depending on the format of the output signal, optical encoders are categorized into two types. These include absolute encoders and incremental encoders.
Usually, inexpensive infrared LEDs are used as light-emitting devices in optical encoders. However, to suppress light diffusion, colored LEDs are sometimes used. Similarly, for applications that require high performance and high resolution, expensive laser diodes are utilized.
From office equipment, medical devices, and machine tools to robots and automated vehicle guidance, the applications area of optical encoders is widening rapidly.
Key advantages of optical encoders:
Thanks to these advantages, optical encoders are being increasingly used for servo control and hollow through shaft type motor control that requires high precision. They also find usage in devices and systems that use large-diameter motors.
