Encoders

25LB22-G is a high-resolution, absolute encoder designed for applications requiring accuracy and precision. It is a rotary encoder that converts the angular position of a shaft into a digital code. The encoder provides 360° absolute position resolution with 26-bit parallel output. The 25LB22-G is commonly used in applications such as motors, large scales and measuring tools.

Applications

The 25LB22-G absolute encoder is typically used in robotics, machine tools, integrated motor drives, and precision engineering applications. It is a common choice for applications that require fast response times because of its superior accuracy and high repeatability. For example, the 25LB22-G can be used in applications such as speed control, position control, automatic piloting, speed regulation, steering, and motion sensors.

Working Principle

The 25LB22-G is an absolute encoder, which means it provides an instantaneous, digital output representing the actual angular position of the shaft at any given time. The encoder has an internal scanner with a number of tracks that are used to generate the encoder’s digital signal. The scanner consists of two or more slots that are spaced at equal increments. When the encoder is rotated, the slots in the scanner are each read as one by one by a rotating mirror and light source. The mirrors reflect light patterns onto sensors that convert the light pattern into a digital code which is then output to the encoder’s processor.

The processor then decodes the information and generates a 26-bit parallel output that represents the position of the encoder at any given time. This output can then be used to control a device, such as a motor, in response to the angular position of the shaft. The 25LB22-G has a maximum output speed of 10 million counts per second, and an output range of 10,000 counts per revolution.

Conclusion

The 25LB22-G absolute encoder is designed for applications that require precise positioning and accurate control. It is commonly used in robotics, machine tools, integrated motor drives and precision engineering applications. Its high-resolution, 25-bit output provides 360° absolute position resolution with a maximum output speed of 10 million counts per second, making it an ideal solution for applications that require fast response times.
