Need help with a Omron relay

I have a Omron G6sk-2f relay how can I determine what each of the 10 pins do?

Datasheet does not show 0 pin as a place pin call out, they have 1 to 12 pins

sorry i meant each of the 10 pins not the 0 pin. I dont see this info on the datasheet, am I missing it somewhere?

page 6 of the datasheet

Thanks for the diagram. I’m just learning about latching relays so how do I read this diagram? If I apply voltage to pole 1 it flips both 9 and 4 over to 10 and 3 and they stay there until I apply voltage to 6? Or am I totally off base?

Hi @dreed10 ,

Correction** @David_1528 has provided valuable insight. Please see updated response:

Thank you for your reply. Pins 1 & 12 are the S or “Set” coil, where pins 6 & 7 are the R or “Reset” coil. Both coils do require the shown polarity in order to energize but are not meant to be powered at the same time. The schematic diagram in the datasheet, like other latching relay schematics are always shown in the Reset state, if you were to apply a pulse voltage to the Set coil, then pin 4 would connect to pin 5, and pin 9 would connect to pin 8. The relay will latch in this state until the appropriate pulse voltage is applied to the Reset coil, in which pin 4 would connect to pin 3, and pin 9 would connect to pin 10 and would remain latched until it were to be “Set” again.

Latching relays are almost always shipped in the reset state also, but this cannot be guaranteed. Shock and impacts to the relay during shipping or installation may cause it to change its contact state.

Great. Thanks for the explanation. When energizing either the Set or Reset coils does the opposite coil need to be disconnected from power first?

Neither coil should left energized with a latching relay because their entire purpose is to hold their state with no power applied. Short 0.01 second long pulses perform the set & reset functions.

For manual activation of set and reset. normally open momentary pushbutton switches are a common method of activating the states.

If your circuit design can allow constant power you should just use normal much less expensive relays.


Got it, thanks. Can this relay handle 120VAC one the output side?

By output I’m assuming you mean the switch contacts.

If the current through the switch contacts is a resistive load of 0.5A or less, the data sheet says it can handle 120VAC. See page 2 of the data sheet linked above.

However if I wanted to guarantee a long life without testing to verify how purely resistive the load really is, I’d de-rate the current limit to 0.25A.


got it…thanks for your help
