outline  

Embedded trackball is an industrial solution for precise control of X, y two-dimensional coordinate information. Its compact design is very suitable for applications in products with strict space constraints, such as keyboard and embedded design.

Usage characteristics  
 

The characteristic of embedded trackball is that it drives the ball to roll through the fingers and drives the pointer on the screen to move. such

It does not need the movement of the whole arm, and the benefit is to reduce the fatigue of the whole hand. And save installation space.

Electrical characteristics  

The conversion from the motion of the embedded trackball to the position coordinates is realized by the photoelectric coding circuit in the trackball. The circuit has the characteristics of high precision, high reliability and long service life. It has ps/2, USB, RS232 and other standard protocol output, and left, middle and right key interfaces.

Product classification  

The embedded trackball can be divided into 16mm, 19mm, 25mm, 36mm, 38mm and 50mm series according to the size of the ball,  
According to the communication interface, it can be divided into PS2, USB, RS232 and square wave output.  
According to the structural characteristics, it can be divided into two types: screw cover type and dust ring type.

Precautions for product selection  

When selecting embedded trackball products, you need to consider the following aspects:

1. How large the sphere matches the product (considering the hand feel, we suggest to select a large trackball as far as possible, and also consider the size of the target moving range)  
2. Whether the installation position for the trackball is enough  
3 what type of communication protocol is used to communicate between the trackball and the host  
4 is there any requirement for the type of trackball connector  
5 is there any requirement for the color of the trackball shell and sphere  
6. Do you have any other special requirements.
