What can relay protection structuring do?

Electronic components, especially relays, need to satisfy many environmental requirements of the market, such as environmental performance, explosion-proof performance, and long life. These requirements ensure the diversification of equipment usage environments.
In response to these requirements, OMRON supports product development that is compatible with each usage environment by providing customers with components that employ several types of protective structures.

OMRON's relays respond to the diversification of usage environments with their protective structures.
