Not sure if this is the best place for this, but I have an electromagnetic application where we are driving 2 coils with 0.2-2.0 amps with TDK Lambda power supplies. The application requires reversing polarity of the current and this is where we are using the ice cube relay. It is critical that the current is controlled down to single-digit milliamp accuracy which is why we are using the Lambdas. We have another test station setup that isn't automated and are finding that we have a significant amount of discrepancy between the automated/ice cube relays and the manual toggle switches with the manual toggle switches being much more consistent/accurate/repeatable. Are there relays out there that are really good for this kind of application, are there others that aren't? I would really appreciate any advise, council on the subject.

Leading manufacturers are aligning their people, processes, and tools from initial product ideation through to field service. They do so by providing access to product and enterprise data in the context of each personâ€™s domain expertise. However, it can be complicated and costly to unite engineering with the factory and supply chain. Download Now

Itâ€™s easy to fall in love with your own CAD design on the computer screen, but itâ€™s how everything fits together off the screen that really matters. Beyond the design, products need to solve real-life problems or provide huge benefits that genuinely merit separating money from wallets. Download Now
