Encoder: Definition and Application for the Industrial World

Based on some of the references I read, I concluded that an encoder is a sensing tool that provides feedback. Encoder devices were created by Encoder Manufacturers to lighten human work. Encoder products convert the motion to electrical signals that can be read by several types of control devices in motion control systems. For example, in an elevator, the encoders notify the controller when the elevator box has reached the correct floor and the correct position. This means the encoder feedback to the elevator controller ensures the lift door opens with the floor. The encoder sends a feedback signal that can be used to determine position, count, speed, or direction. The controller can use this information to send commands for specific functions.

Have you ever seen an automotive company when assembling a car automatically? We may wonder why the robotic arm can do the welding on the right part and on time. Well, that’s because on an automated assembly line, the encoders provide motion feedback to the robot. On an automotive assembly line, this could mean making sure the robotic welding arm has the correct information to weld in the correct location. All systems are run continuously over a long period.

One type of encoder that is often applied in industry is a rotary encoder. Rotary encoder is a precision measurement of the displacement angle sensor based on the principle of electromagnetic induction, rotor and stator winding. Rotary encoder for speed and position feedback sensor mainly applied in servo motor, induction motor, elevator traction machine, elevator door machine, axis mechanic, etc. Rotary encoders manufactured by Encoder Manufacturers aim to meet the needs for speed and feedback transfer of automation control to ensure high precision and stability in the operation of industrial machines. The presences of Encoder Manufacturers are indirectly able to help manufacturing companies increase productivity efficiently and ensure safe operations.

The manufacturing industry will become a pillar of a country’s industrial progress. Modern industry has left behind the old production system, which always consumes a large amount of energy and produces only a small scale of products. The encoders that are applied to all industrial machines help companies produce large quantities of goods quickly, precisely, and efficiently. Encoder products continue to develop, and they can be applied to a wider range of industrial field such as, industrial control, environmental protection, agriculture, multimedia imaging, aviation, and many more.

In any industrial application, the encoder plays a very important role. The digital signals are generated by the encoder and sent to the controllers. Then, the controllers send signals to the machine to perform a certain function continuously.
