Encoders

An encoder is an electronic device used to convert data from one form to another. This can be done in two ways: either by changing the data\'s physical form or by encoding the data in an alternate code, such as binary or hexadecimal. Encoders can be used for a variety of applications, such as for robotic arms and machine tools, where motion needs to be controlled with precision.

20SG2AC-G2AC-P Application Field and Working Principle

The 20SG2AC-G2AC-P is a single-turn optical encoder developed by Avago Technologies, which is used in many industries, including robotics and machine tools. It has a maximum resolution of 1024 pulses per revolution, and has a maximum speed of 3000 RPM. The encoder is designed with an integrated circuit (IC), which is responsible for detecting the movement of the encoder’s shaft and generating a signal that is read by the host controller.

The 20SG2AC-G2AC-P has two output channels. Channel A is a sine-wave output, while Channel B is a square-wave output. The sine-wave output is typically used for velocity sensing applications, while the square-wave output is used for position sensing. The encoder uses a binary code wheel to detect motion, with two output signals – A and B. These signals are sent to the external controller, which interprets the signals as the position of the encoder’s shaft.

The 20SG2AC-G2AC-P is powered by an external supply voltage and requires a ground connection. The voltage range for the supply is from 5 VDC to 24 VDC. The encoder also has stand-by and shutdown control lines that can be used to power up the encoder and control its operation. The encoder also comes with an ESD protection device that is designed to protect the encoder from electrical shock and vibrations.

The 20SG2AC-G2AC-P can be used for a variety of motion control applications, such as robotics arms and machine tools. Its high resolution ensures that movement can be accurately detected and controlled. The encoder is also designed to be resistant to electrical interference and vibration, which makes it suitable for use in harsh environments. Additionally, the encoder is designed to be easy to integrate into existing systems with minimal effort. This makes it an ideal choice for a variety of motion control applications.
