We will select the optimal probe that is less likely to cause contact failure for wire harnesses of various shapes.
In wire harness continuity testing, do you have concerns such as: "There are channels where contact is unstable due to terminal shape," "When I increased the probe load, it deformed the terminal," "Due to contact failure, good products are misjudged, increasing rework costs"? The causes of contact failure include: - Mismatch between terminal shape or material and the probe - Load settings that are too weak to avoid terminal deformation - Wear on the probe tip - Adhesion of foreign substances and various other factors, making it difficult to identify the specific cause. In particular, the shapes of wire harnesses are diverse, and selecting the appropriate probe for each is very challenging. Therefore, we collect your workpieces and the probes currently in use, and conduct experiments on contact resistance and other factors using our own equipment. We visualize "why contact failure occurs" with data and identify the root cause. Based on this, we propose the optimal probe shape and load conditions for your usage conditions and work characteristics, and we provide free support all the way to the selection that leads to actual improvements. Please feel free to contact us through the inquiry form.

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.
