The Omron G4A Relay is a SPDT (Single Pole Double Throw) type electromagnetic relay that allows a low-voltage signal to control a higher-voltage load. The relay’s design ensures safe and efficient switching of electrical circuits, making it ideal for controlling both small and large electrical devices. Typically used for applications involving significant current or voltage, such as in industrial automation and household appliances, the G4A series relay stands out for its combination of high load handling capacity, compact design, and long operational lifespan.
