High current Omron types G3VM-61GR2 and G3VM-61HR1 match the performance of comparable Omron electromechanical relays, and exceed that of competing solid state relay alternatives. Key features are the low on-resistance compared to electromechanical devices and their low susceptibility to external magnetic interference. A key feature is the fast switching time – with a Ton / Toff of 3 msec/0.5 msec for the GR2 and 5 msec/1 msec for the HR1.

The G3VM-61HR1 is aimed at higher power applications. Packaged in a 6-pin SOP it can switch currents of up to 3.3A AC at 60V and has an on-resistance of 30 milliOhms. Using a double current connection configuration for DC loads, the device can carry up to 6.6A DC with an on-resistance of 8 milliOhms. This is a 43% greater load than the previous G3VM-61HR.

The G3VM-61GR2, in a 4-pin SOP package, is designed for signal switching of digital and analogue signals. It can switch currents of up to 1.7A AC, 70% more than the previous G3VM-61GR1, with an on-resistance of 80 milliOhms.
