To protect expensive devices, selecting the appropriate contact probe is essential!
The selection of high-current probes used for power device conduction tests needs to be done carefully. Incorrect selection can lead to abnormal heating or sparking, potentially resulting in significant losses such as damage to expensive devices or equipment failure. There are mainly two key points to consider when choosing the appropriate probe: 1. Compatibility of specifications: It is important to select a probe that has sufficient margin for the usable current in the limited space due to device miniaturization. 2. Contact resistance between the probe and the workpiece: Even slight contact resistance can cause measurement errors or abnormal heating, so it is crucial to choose a probe that can maintain stable contact with the workpiece. However, many customers are unsure about "what specific criteria to use for judgment." Therefore, Sankei Engineering offers a "Free Probe Selection Service." We will actually take your measurement workpiece, measure the contact resistance with our equipment, and based on the data obtained, we will select and propose the most suitable probe for your usage environment. Inquiries during the comparison and information-gathering stages are also welcome. Please feel free to consult us through the contact form on our website.

Company information
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.
