POGO PIN is energized or turned on, most of which are in contact with the copper wall through the POGO PIN needle obliquely downward, and the POGO PIN spring bears a small amount, so the inner wall of the copper sleeve is required to be smooth. If the POGO PIN factory is made into a non-beveled surface, but the bottom is flat, most of the current must be conducted through the spring, and the requirements for the spring will be very high. Of course, it is necessary to ensure that the signal current is unstable when the current suddenly increases. Let's follow the editor of Cheng Yuxin to understand the points we should pay attention to when purchasing POGO PIN.

1. Size of POGO PIN: The size of POGO PIN is determined by the strength of the design, current load, and shape, but a large diameter usually increases the cost significantly. The standard POGO PIN is usually 1.5 for the needle and 0.9 for the needle, which is the most economical choice.

2. The height of POGO PIN. The height of the POGOP IN is determined by the working height, that is, the height during working compression and the accuracy of the matching parts during installation. Usually, the compression stroke is about 70% of the total stroke, and the common working stroke is 1.0mm.

3. POGO PIN current load. POGO PIN current load requirements are different, and the entire design parameters of POGO PIN should be changed and adjusted accordingly.
