The Omron G4A relay series is designed for use in various industrial and commercial settings. It typically features a coil voltage ranging from 5V to 24V DC, depending on the model, which is suitable for most standard control circuits. The G4A relay series supports a wide range of switching capacities, with the contact ratings commonly set at 10A or 5A, depending on the specific variant. This ensures that the G4A relay can handle moderate to high power loads efficiently.

    The contacts of the relay are usually configured as Single Pole Normally Open (SPNO) or Double Pole Normally Open (DPNO), making them highly adaptable for different switching applications. The switching mechanism is a standard electromagnetic coil that, when energized, pulls a contact arm to establish or break an electrical connection. These relays can be used for both AC and DC circuits, and the contact material is typically silver alloy, which is designed to withstand significant wear and tear during operation.
