Omron's new high-current G3VM-61GR2 and G3VM-61HR1 relays match the performance of comparable Omron electromechanical relays and outperform competitors' solid-state relays. Key features include low on-resistance compared to electromechanical devices and low susceptibility to external magnetic interference. A crucial feature is their reduced switching time, with a Ton/Toff of only 3ms/0.5ms for the GR2 and 5ms/1ms for the HR1.
The Omron G3VM-61HR1 is designed for higher-power applications. This device comes in a 6-pin SOP package, can switch currents up to 3.3A AC at 60V, and has a forward resistance of only
30 milliohms. Thanks to its dual-current connection configuration for DC loads, the device can drive up to 6.6A DC with a forward resistance of only 8 milliohms. This is 43% higher than the previous G3VM-61HR model.
The G3VM-61GR2, supplied in a 4-pin SOP package, is designed for switching digital and analog signals. It can switch currents up to 1.7A AC, 70% more than the previous G3VM-61GR1 model, and its on-resistance is 80 milliohms.
Andries de Bruin, Product Marketing Director for Europe at Omron Electronic Components Europe, commented: “More and more applications are opting for solid-state MOSFET relays. Among the reasons for this are their resistance to magnetic field disturbance and their low susceptibility to EMC interference in industrial environments. These devices are setting new standards in electrical performance, making them a viable alternative to electromechanical relays in many new applications.”.
