Best Relay?

Hi, does anyone know which is the best 5-6V relay out there for the price. It needs to contact a 6V connection and must not corrode fast.
thanks all.... Basil
Do you Yahoo!?

just ware out. for harsh environments or outdoor use, have you thought
about using solid state relays or even power mosfets?

Environmental effect can be counter acted with different means. You
can add a grease to the connectors that prevent oxidation, or use
solder jounts and liguid electrical tape or even epoxy.
You can put the stuff into a sealed container for not too much.
But the best relays are the ones that fit, that you can buy easily
and find a good supply.
The worst are the ones you buy, but cannot find replacemets for.
I would also look into what you are doing. can you use silicone ?
SCR, Darlington, Triac ? they are often lots cheaper and much
easier to buy and seal.

best value for money, miniature industrial quality relays I have come
across is one widely used for model railroads. Note it also comes with
a 5V coil if you request it. I think it is spec'd up to 10A at for AC
loads.
I sell lots of them to other model railroaders for $1.99.

I'm not sure what you mean by "corrode". Are you talking about
environmental conditions (rain, water, corrosive gasses, etc) or are you
talking about contact erosion from arcing?
How much current are you switching? Inductive or resistive load?
The two relays we use here by the tens of thousands are both single pole
relays.
The little relay is a JS1 or JS1E from Aromat (NAIS). It is rated at 8A or
10A (depending upon application) and is available with a DC coil rating of
5V, 12V, 24V, 48V (all dc).
The larger one is an AZ2150 (form C - SPDT) or a AZ2150A (form A - SPST NO)
from American Zettler. The form C part is rated for 20A on the normally
open contact and 15A on the normally closed contact. The AZ2150A is rated
for 30A. These are also available with coil voltages of 5V, 12V, 24V, 48V
(all DC).
Many people make the larger relay - the original is a Potter & Brumfield
T90 series but Omron and Takamisawa also make compatible versions. I think
we've used that style of relay from all the major manufacturers but have
settled on the American Zettler version because of slightly higher current
and voltage ratings certified with UL and CSA.
Both of these relays are epoxy sealed - they will work wet so long as you
seal the pins.
These have been great parts for us - I'm guessing that we've used about
75,000 pieces over the past 5 years or so.
