Product Overview
Mouse scroll wheel magnets are compact permanent magnets used in scroll wheel mechanisms and other small motion-sensing assemblies. They work with magnetic sensors to detect wheel rotation and provide the magnetic signal needed for electronic motion detection.
Space inside a computer mouse is limited, so the magnet needs to match the scroll wheel and sensor assembly accurately. Size, magnetic strength, and pole orientation can all affect the sensing response. For this reason, mouse scroll wheel magnets are commonly made to specific design requirements rather than selected as standard components.
Jinconn provides custom mouse scroll wheel magnets based on customer drawings, samples, 2D/3D files, or technical specifications. Magnet dimensions, magnetic grade, coating, polarity, and magnetization direction can be adjusted to suit different product designs.
The magnets can also be produced in different shapes and sizes to fit specific scroll wheel structures and sensor layouts. For projects with limited installation space, the magnet can be designed around the available assembly area and required sensing distance.
Although commonly used in computer mice, compact magnets of this type can also be adapted for other applications involving rotational sensing, position detection, or small-scale magnetic coupling. Custom production is available for prototypes, small batches, and volume orders.
Material: Neodymium (NdFeB)
Mouse scroll wheel magnets are commonly manufactured from NdFeB because of its high magnetic energy density and compact size. The material provides strong magnetic performance while occupying very little internal space, making it suitable for miniaturized electronic assemblies.

FAQ
Q1. Can you manufacture magnets according to our drawing or sample?
Yes. Customers can provide 2D drawings, 3D files, physical samples, or technical specifications for custom magnet production.
Q2. Are these magnets only suitable for computer mice?
No. Although mouse scroll wheels are a key application, customized versions can also be used in rotary sensing, position detection, compact electronic assemblies, and other mechanisms requiring a small permanent magnet.
Q3. What information should I provide for a custom mouse scroll wheel magnet?
A drawing, sample, dimensions, magnetization direction, required magnetic performance, sensor type, and application environment are helpful. If some specifications are unavailable, Jinconn can review the application requirements and help determine the appropriate magnet design.
