Review on Omron General Purpose Standard Polarity by Calvin Booker

I bought these relays to replace some common relays I had on a project. The common relays felt warm about twenty minutes after powering up. Since my project required the relays to be constantly energized for several days, I felt uncomfortable using them. I pulled out those relays and plugged in an Omron relay. I was totally amazed at this difference. Omron relays rarely heat up after being energized for a long time. Of course Omron relays are more expensive but knowing that they are well constructed and reliable gives me confidence in the product. Omron relays are commercial/industrial grade.
