We respond to the need to minimize the variability in resistance values specific to contact probes as much as possible.
By using a bias structure and inserting a ball, we were able to increase the contact pressure on the inner wall of the pipe; however, this also resulted in significant damage to the inner wall, leading to issues such as probe sticking when used repeatedly. To address these disadvantages, Seiken combined parts using precision machining technology instead of balls, thereby reducing damage to the inner wall of the pipe while maintaining the characteristics obtained through bias. Furthermore, by miniaturizing the parts, we can also create a bias structure compatible with P=0.4mm. We respond to the need to minimize variations in resistance values specific to contact probes, such as in low-resistance measurements. *For more details, please refer to the PDF document or feel free to contact us.*
