A. Outer diameter: The maximum diameter of the encoder's outer shape, usually standard 38mm or mini 15mm.
B. Output shaft diameter: The diameter of the upper shaft of the encoder is generally standard 6MM and 8MM, and mini 3MM.
C. Output shaft length: The length of the upper shaft of the encoder that extends out, with a standard of 15mm, but there are also blind holes that do not exit the shaft and are concave inside.
D. Axial axis load: The tension or thrust exerted on the upper shaft of the encoder, exceeding which force may damage the equipment.
E. Radial axis load: The vertical pressure exerted on the upper shaft of the encoder, exceeding which force may damage the equipment.
F. Allow axial movement: The maximum range of allowable shaking for the upper shaft of the encoder.
G. Protection level: dustproof and waterproof level, such as IP54, IP67, etc.
