High current contact probe for battery charge and discharge testing.
For testing EV batteries and cylindrical cells! Solving challenges with a rich lineup and custom sizes.
In the charging and discharging tests of EV batteries and cylindrical cells, do you have any concerns such as: "I am looking for a probe that can withstand long hours of continuous current" or "The contact area of the electrode is small, and standard products do not fit"? Sankei Engineering offers a wide range of high-current contact probes designed to solve these issues for battery charging and discharging tests. Our catalog includes a broad lineup, from a minimum diameter of φ5.0mm (usable current under 20A) to a maximum diameter of φ22.0mm (usable current under 300A). Furthermore, for special electrode shapes that are difficult to accommodate with catalog products or when the contact area is small, we can manufacture custom probes by changing the tip diameter and shape. We also provide design and manufacturing of products optimized for your usage environment, including adjustments to spring load and size design tailored to fixtures. Inquiries during the comparison and information-gathering stage are also welcome. Please feel free to consult us through the contact form on our website. *Care should be taken when selecting high-current probes. For selection points and precautions, please refer to [Battery Selection Points URL].

Contact probes are indispensable for the manufacturing of all precision instruments. Since entering this field 50 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.
