Industrial encoder accessories, encoder wheels, and encoder meter wheels are all components used in conjunction with encoders to help measure the position, speed, or direction of a rotating shaft or linear motion. Encoder meter wheels are similar to encoder wheels, but they have a tire or tread that makes contact with the being measured. This type of encoder is commonly used for measuring conveyor belt speed or other linear movements. Encoder wheels are typically made of aluminum or plastic and have evenly spaced slots or holes around their circumference. As the wheel rotates, an optical or magnetic sensor detects changes in the pattern of slots or holes and uses this information to calculate the shaft's rotation angle or linear travel distance.
