## How to display magnet size?

• [1] The circular size generally uses D to indicate the diameter (because it is a special symbol for convenience, most people use D instead of Φ). For example, D10X2MM indicates a magnet with a diameter of 10 mm and a thickness of 2 mm. X This is the mathematical symbol “multiplication sign”.
• [2] The size of the square is length X width X height. Generally, F represents the square. For example, F60x20x10MM means that the length of the square magnet is 60 mm, the width is 20 mm, and the thickness is 10 mm. Generally, the last number indicates the magnetization direction of the square magnet by default. For example, for the F60x20x10 square, the magnetization direction is 10MM. That is, the height direction is magnetized. NS is on the two largest faces, that is, 60×20 faces.
• [3] The size of the ring is the outer diameter DX inner diameter DX height. For example, the ring magnet of D32XD18X6 indicates that the outer diameter is 32 mm, the inner diameter is 18 mm, and the height is 6 mm. Height is also called thickness. At present, the ring is also divided into straight holes and countersunk holes. The holes of the straight holes are drilled vertically, and the countersunk holes are divided into large and small holes, and the depth of the large and small holes are commonly known as screw holes.
• [4] Sphere magnets are represented by a simple diameter D. For example, D5MM means a magnetic ball with a diameter of 5 mm.
