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.
PCB Cleaning
Sealed with resin to allow cleaning, contributing to equipment maintenance.
Application example
The PCB is cleaned during maintenance to prevent electrical leakage.
Water-proof / Moisture-proof
Sealed with resin to prevent water from entering.
Application example
Used in high temperature and high humidity, or in environments subject to water.
Note: Potting and coating are not within the scope of the warranty, so please consult your OMRON representative.
