Encoders: Application Field and Working Principle

Encoder is an important part of rotor speed, position and perpendicularity measurement. It could help in realizing the control accuracy and reliability which is required for modern automation and productivity improvement. This article will introduce the application field and working principle of H25D-SS-300-ABC-5V/V-SM16-EX encoders.

What is an encoder?

An encoder is an electromechanical device which is used to generate digital signals in response to motion or position. It could convert the mechanical motion, like angular displacement, linear displacement into digital signals, such as pulse sequence, parallel code, pulse width modulation (PWM), frequency, voltage signals, etc.

Application field of H25D-SS-300-ABC-5V/V-SM16-EX Encoders

The H25D-SS-3000-ABC-5V/V-SM16-EX encoders are used in various industrial applications, such as automation, biomedical engineering, robotics, automobile control, and mechatronics. It is a miniature, high-precision, robust, and reliable encoder that could effectively measure activities, like rotor speed, position, diameter, and perpendicularity of a rotating shaft.

Working Principle

The H25D-SS-300-ABC-5V/V-SM16-EX encoder utilizes a thick-film technology to reach an accurate and robust measurement. The encoder is composed of three main components: a contact piece, a pick up sensor, and an analog-to-digital signal processor. The contact piece, which is typically connected to the rotating shaft, has two transversal grooves. The grooves are said to be information carriers as they generate pulses in response to the speed of the shaft. Then the pick-up sensor could read and convert these pulses into voltage signals. The analog-to-digital signal processor inside the encoder could then convert these voltage signals into digital signal. These signals are in the form of pulse sequence, parallel code, pulse width modulation (PWM), or frequency signals. This digital signal could then be sent to the receiver where it could be interpreted and used as a parameter in controlling the power components.

Conclusion

The H25D-SS-300-ABC-5V/V-SM16-EX encoders are high-precision and reliable encoders that are specially designed to measure rotor speed, position, diameter or perpendicularity of a rotating shaft. Its thick-film technology and components, such as pick-up sensor and analog-to-digital signal processor, make it suitable for industrial applications like robotics, automobile control, and mechatronics.
