For those who need non-magnetic and lubricating properties, please give it a try!
With the advancement of high technology in devices that are sensitive to magnetism, there has been a trend towards higher density and higher performance in measuring and analytical instruments. As a result, there is a growing demand for non-magnetic properties not only in the main functional components but also in connectors and contact parts that have been previously overlooked. Additionally, with the economic growth of emerging countries, the introduction of the aforementioned measuring and analytical instruments is progressing. However, due to the high cost of the equipment itself, the frequency of updates is much slower than in developed countries, and there is a desire for longer lifespans. Therefore, we have developed a non-magnetic coating that enhances the longevity of insertion and removal cycles and reduces contact resistance, improving the specifications as outlined below: - Maintains low contact resistance even after 60,000 sliding tests - Solder wetting properties and contact resistance are equivalent to conventional products! - Non-magnetic just like conventional products! *For more details, please download the catalog or contact us.

basic information
Our company has improved various issues associated with traditional plating. 【Traditional Plating】 Nickel cannot be used because it is a magnetic metal. When gold plating is lost during insertion and removal, nickel comes to the surface, but nickel oxidizes and increases contact resistance. Connector lifespan is approximately 20,000 cycles. 【Developed Plating Coating】 By using a palladium alloy, we have successfully avoided magnetic issues. Even when gold plating is lost during insertion and removal, palladium, which has similar properties to gold, ensures that contact resistance does not change. The palladium alloy has a moderate height, resulting in a successful connector lifespan of 60,000 cycles.
