SMH SY50 Series 8 AWG 50A Breakaway DC Power Connector

Is there a male/female scenario with these plugs?

Asked by: PBTower

My application is under the hood of a car where the connectors may be exposed to harsh environments (i.e. water). How can I keep these dry?

Asked by: SoftwareDrone
You don't have to keep them dry. I have a connector attached to the underside of the rear bumper of my pickup (for a trailer winch) where it gets wet and dirty for years now and it doesn't seem to matter.

Asked by: HardStart
If you need an SY50 model, this will work. These are available from SMH in different colors, although we only offer the gray option.

Does the connector come with rubber cap?

I have seen these with captured rubber dust caps, both red and black in color. If not, how do you order the caps?
Asked by: ST1300P
We do not currently carry any caps for these. I will forward the suggestion to our new products guys though, Suggestions to improve our product lines are always welcome.
