power relay number matching

[nomoresonys]

having a little trouble figuring out what relay will substitute for my power relays on a pcb, I am replacing both that are side by side, thanks.

Re: power relay number matching

example: G2R-1A-E-T130DC24, G2R-1A-T130DC24, GR2-1AE-DC24, GR2-1-E-DC24, all seem to look the same, the same, I guess I'm wondering what the numbers mean, and if I have to use the same exact ones I took out if I'm replacing both, thanks.

Re: power relay number matching

get the datasheets to understand the meaning of the numbers.

Re: power relay number matching

Have you tried to use GOOGLE with at least one of those names, or parts of those codes?

I just entered G2R-1A-E in google and first result that shows up was G2R series of relays made by Omron.
Then page gives you the datasheet which tells you the meaning of those digits right on the first page:

etc etc etc

Man, do some search before asking such questions

Re: power relay number matching

I did plenty of search, if you think you have to be RUDE "DO NOT RESPOND"!!!

will do stj, thanks for the reply, and THANKS for not being rude, some others could take a lesson.

Re: power relay number matching

Well, you obviously didn't, or you don't know how to search.
Here's the search results for the exactly first code you've written in your post :



Any link on that first page will link to the datasheet, or tells you that it's made by Omron and you can then go on Omron's page and get the datasheet.

And I can be as rude as I want to be, there's no rule saying I can't.

Looky here troll, if you can't help people without developing diarrhea of the mouth, then buzz off, as in go play in traffic.

Re: power relay number matching

I bought G2R-1-E-T130 12VDC cheap on eBay but Google was not my friend, nor the Omron datasheet to figure out the "T130" portion of the part number.
Looking at it: SPDT (1C) high-capacity, PCB mount, flux protection, unsealed, but I have no idea what the "T130" suffix means.

Re: power relay number matching

Google was not my friend,

google is nobody's friend,
use duckduckgo or yandex

Re: power relay number matching

T130 means it's rated for maximum 30V DC @ 16A.
If you bought it cheap on eBay, doesn't matter anyway, it's probably fake or was recycled from some device and you have no idea how many times it was turned on/off and how burned up/oxidized the contacts are inside.

Re: power relay number matching

Google works just fine.
From Omron master catalog:
Coil Class B insulation (130c).
5. Suffix T130 rated at 130°C
I myself use Class 'F' 155c rating in my products design, I use lots of Omron relays.

Page 1:
Note: 1. AgInSn and gold plated contacts available.
2. Bifurcated button available.
3. For individual product agency approvals consult factory.
4. Class B coil insulation available

G2R-1A-E is the HIGH CAPACITY which is 16A Contact rating, see Page 1 and Page 3.

Re: power relay number matching

Thanks budm, I couldn't find that number in the datasheets.
It seems to be for a UL Class B (130°C/265°F) standard for coil insulation.

The relays I got from a Ham radio operator on eBay, have a clear case and I can see they are new and look like Omron quality.

Actually, I use DuckDuckGo instead of Google because I dislike being tracked with search queries, websites visited and the analytics.

Re: power relay number matching

The standard coil insulation is <130c, 75~85c is typical.
I use Duck also but I get less hits than Google, and that is correct, Google does track your search info but for me at work I could not careless, they can track the company I work for all they want.

Re: power relay number matching

duckduckgo has config bits.
by default it will search the country your originating from.

if you embed it in your browser then set it like this:
https://duckduckgo.com/?q=%s&kp=-1&kl=wt-wt&kv=1&kh=1

the q=%s is the search-string,
the rest of it is for global search, no localisation, no sensoring and no limitations.
