High current probe
**Overview** The contact part is made of a silver alloy with good conductivity. Depending on the size, it can handle currents from 15A to 300A. In the case of high current conduction, unexpected events may occur at the probe tip and the surface of the workpiece due to heat generated from contact resistance. Please consult us in advance for high current applications. Additionally, please refer to this for considerations during selection. We offer four types for high current applications. ● CP Series → The tip material of the general-purpose CP series is AgW. ● CPM Series → The bush section is a nut-type with threaded processing. ● CPMM Series → A large probe capable of conducting over 70A. ● Coaxial Type → A probe compatible with high current that allows for four-terminal measurements. Approximate dimensions are displayed in the downloadable materials. We accept custom orders for size changes and other requests, so please contact us.

Company information
Contact probes are indispensable for the manufacturing of all precision instruments. Since entering this field 30 years ago, Sankei Engineering has actively worked on "technologies and products that cannot be imitated by other companies," accumulating unique know-how. Particularly in specialized areas that require high precision, such as measurements under high current, high voltage, and extreme temperatures, it is difficult to meet the demands without our outer spring type (integrated) contact probes, establishing a significant competitive advantage in this market.
