This design features a unique 4-pin structure with a groove base. This configuration offers two key advantages. On the one hand, the baseplate can take load advanced technological controllers, integrating electronic units and sensing components. This results in a finished product that is taller than standard PCB controllers. Therefore, it’s crucial to consider the length of the base pins and other features.

On the other hand, the groove design allows the metal pins of the PCB to have a larger contact area compared to traditional 4-pin bases. This enhancement improves the stability and reliability of electrical devices. Additionally, the silicone seal design enhances the waterproof capabilities of the finished product, and addressing after-service-waterproofing concerns.
