custom optical rotary encoder disk
A custom optical rotary encoder disk is used in an optical rotary encoder, which is the equipment used to determine the rotation of a shaft. The disk’s outer surface is usually transparent, for example, made of glass or a transparent plastic coat. They may have the pattern applied on an opaque base material that only has patterns of inclined transparent and opaque stripes, dots, or other divisions.
Features of optical rotary encoder disk
Material: Normally, glass for higher accuracy, but plastic kind is also employable for economic return.
Tracks: Multiple tracks can be there for high resolutions or embedding other data like direction also.
Resolution: Depending on how many lines or segments are drawn on the disk surface, the more patterns on the disk surface usually mean a higher resolution disk.
Advantages of Optical rotary encoder disk
1. High Precision and Accuracy
Rotary encoder disks can come with very high numbers of graduations and so can be used to measure angular position, rotational velocity and direction.
Absolute encoders: Give exact position even when power failure.
Incremental encoders: Have the capability to provide accurate relative position and a relative speed.
2. Non-Contact Operation
In optical and magnetic encoders, the sensor does not come into contact with the disk, which reduces wearing and damages the disk.
3. Versatility
Rotary encoder disks can be used in an extensive range of applications for simple personal use products, for instance, mouse scroll wheels and in sophisticated industrial applications such as Computer Numeric Control machines, robotics among others.
4. Compact Size
Some of them can be made flexible to occupy very small areas and thus can serve very well applications that requires a very small area.
5. Real-Time Feedback
Rotary encoder disks are used to give immediate data about motion so it is useful for real time applications such as automation in machine or motor.
6. Durability
Recently developed disks, such as metal or industrial plastic, possess high physical endurance and can endure conditions like high temperatures and vibration.
7. Customization
Encoder disks can be user-defined in terms of resolution, patterns and materials depending with the application needed.
8. Wide Range of Output Options
It accommodates different output forms inclusive of analog or digital pulses or serial alongside other forms of communication for simple coupling with the control frames.
9. High Speed Capability
Rotary encoder disks are usable at high rotational speeds and do not affect the precision making it suitable for dynamic systems.
10. Cost-Effectiveness
Rotary encoder disks may provide more cost effective approach to motion sensing than other technologies when reference accuracy is needed.
