![]() There are also several mechanisms for converting physical changes to electrical data in an encoder: resistive, mechanical, magnetic and optical, with optical encoders being the most commonly seen in manufacturing.Īn optical encoder contains at least one light sender and one light receiver to convert physical movement into electrical signals for the controller to process. No matter the method of conversion, the encoder will always either be a linear or a rotary encoder. ![]() The signals they send are used to activate different outputs from the controller, or PLC, at the correct moments.Įncoders work by feeding the control device electrical information based on one of two different systems as mentioned above, rotary or linear. Motor encoders are beneficial in several ways, for example, linear encoders are often used in track applications and allow CNC machines and 3D printers to precisely create parts and rotary encoders make robotic arms possible in the manufacturing industry. They allow for precise measurement of the moving parts in a system. Encoders play a pivotal role in making autonomous machinery function properly. They can be found in everything from robotic arms to 3D printers. ![]() ![]() A motor encoder is a device that logs position data for a control system in automation, or for any machine that includes a motor, where location data is needed. ![]()
