An optical encoder is an electromechanical device with mechanical input and electrical output, which provides multiple digital signals proportional to the regular displacement of the input shaft. There are two types of optical encoder namely incremental encoder and absolute encoder. Incremental encoders are commonly used incremental encoder utilizes two sensing channels (A and B) to sense the angular position of the shaft, generates square waves corresponding to each incremental rotation of the shaft. Furthermore, the absolute encoder is positioning encoder provides absolute positional information and periodic information of the disc, holds the positional information when the power is switched off. An absolute encoder is classified into two types, single-turn absolute encoder, and multi-turn absolute encoder.
The global optical encoder market is estimated to be valued at US$ 2,184.3 million in 2021 and is expected to exhibit a CAGR of 8.7% over the forecast period (2021-2028).

Market Trends
Encoder manufacturers are focused on the standardization of output drivers on a common set that is electrically protected, more robust, and have higher drive capabilities compared to those of the past. Moreover, optical encoders are becoming increasingly compatible with buses either existing fieldbuses or emerging Ethernet-based buses. The development of intelligence within the rotary encoder is one of the major trends in the market. Optical encoders are becoming increasingly versatile in operations, owing to development of programing and diagnostic capabilities.
Currently, incorporating optical encoders and advanced motion control systems are begin increasingly adopted, particularly in industries such as offshore equipment, construction, military & aerospace, and alternative energy systems. Furthermore, manufacturers are developing advanced optical encoders and other motion sensors, in order to cater to demand reliable operations under extreme conditions (dirty, wet, and very hot and cold) coming from these sectors. Increasing deployment of magic encoders in high-volume industries such as household appliances, automotive and fitness equipment is another major trend in the market.

Global Optical Encoder Market: Restraints
Major concerns regarding security are expected to restrain growth of the global optical encoder market during the forecast period. Optical encoders are complex electronic devices equipped with integrated circuits, photo detectors, and LED, which makes them vulnerable to damage in case of electrical disturbances. This susceptibility makes them less tolerant of mechanical misuse and also constraints their temperature limits. In fact, the mechanical fragility is probably the biggest drawback of optical encoders. The main component of optical encoders is a thin glass disk, which is susceptible to damage due to excessive shock or vibration.
