Relay question

firealarmfreak

Hey im aware this is a basic stamp forum but mabe somebody knows how to answer my relay question since people often use relays to activate high load devices from the basic stamp.

I have this relay here: http://octopart.com/info/Omron/G5V-1-DC5 and it is SPDT (Single Pole Double Throw) and It should have 5 pins but according to the data sheet that is accessable through the link i provided, it has 6 pins and I am not sure which ones are Normaly Open, Normally Closed, Coil and Common.

If anyone can post a diagram showing me and showing me how to find out that would be great.

Thanks.

Chris.

When in doubt, ohm it out.·

The coil has a measurable resistance, a couple hundred ohms.· Then, the remaining terminals are the NO, NC, C; you can find which is which by process of elimination (mini-grabbers or clips instead of probes is a real help at this stage),·"ohmming" between them, turning the coil on/off.

you may want to check out this link (even if your part has only five pins, it should be compatible if it is of this type):

hope this helps

The datasheet in the link has no pin-out.· Any other data sheet would provide that.· The diagram usually is on the relay itself as well.· For the particular relay you have-

5 & 6 are internally connected together·and are the common·side switch.

1 to 5/6 is normally closed

10 to 5/6 is normally open.

2 & 9 are the coil.


From bottom:

1···· 2············· 5

10···9··············6
