What is Encoder? Innovation in Motion and Sensing Technology

Heard the term “encoder” but never clearly got the answer, but what is it exactly? They have existed since the early 1900s, but digital encoders' development and widespread use began in the 1960s.

Today encoder technology is used in diverse industries, including robotics, solar energy, automation, medical, aerospace, and manufacturing, to improve system performance and accuracy. So, what is encoder, in plain words? A technological device that converts physical motion or position into digital signals

Why, nowadays, are encoders vital in motion and sensing technology? They provide real-time feedback on position, speed, and direction, enabling machines to perform precise movements.

Do you know how encoders work? 

Here is a brief overview. Encoders consist of a sensing element detecting motion or position and an electronic circuit translating the sensing element's signals into digital information. Usually, disks with slots or magnets these elements detect the motion or position of a light source or object. Later the sensor sends electrical signals to an electronic circuit that translates them into digital information.

Types of encoders

There are two types of encoders: absolute and incremental. Absolute encoders provide an exact position reading, while incremental measure movement relative to a reference point.

Real Pros of encoder technology

• Accuracy and precision - technology provides precise and accurate measurements of motion and position, ensuring that machines move with accuracy and consistency.

• Durability and reliability - most devices are able to withstand harsh environments and heavy use without losing accuracy or precision.

• Improved system performance - encoders enable machines to perform complex movements and tasks with greater speed and accuracy, improving system performance and productivity.

• Compatibility - encoders can be used in various systems, from simple mechanical devices to complex computer-controlled systems, making them versatile and adaptable to different applications.
