Abstract
A reflective photoelectric encoder includes a reflective photoelectric switch and a code disk. A surface of the code disk includes a first zone and a second zone. The first zone includes alternating first reflective areas and first non-reflective areas. A width of each first reflective area along a circumferential direction of the code disk is equal to a width of each first non-reflective area. The second zone comprises one second reflective area and one second non-reflective area, adjacent to each other, their widths along the circumferential direction being equal. The width of the second reflective area is twice the width of a first reflective area.

A reflective photoelectric encoder, comprising a reflective photoelectric switch and a code disk, wherein:
- a surface of the code disk includes a first zone and a second zone, the first zone includes a first reflective area and a first non-reflective area, and the second zone includes a second reflective area and a second non-reflective area;
- in the first zone, an area between any two adjacent first non-reflective areas is the first reflective area, and a width of the first reflective area along a circumferential direction of the code disk is equal to a width of the first non-reflective area along a circumferential direction of the code disk;
- the second reflective area and the second non-reflective area are adjacent to each other, and a width of the second reflective area along the circumferential direction of the code disk is equal to a width of the second non-reflective area along the circumferential direction of the code disk;
- and
- the width of the second reflective area along the circumferential direction of the code disk is twice the width of the first reflective area along the circumferential direction of the code disk.
