SMH SY175 Series 1/0 AWG 175A Breakaway DC Power Connector
SMH SY175 Series 1/0 AWG 175A Breakaway DC Power Connector is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Perfect for my applicationI wanted to be able to move my deep cycle batteries between my car (for charging) and my trailer (for power while camping). No need to run high-power leads from car to trailer. These fit the bill perfectly. They provide no-worry secure connection in both environments and can't be plugged in wrong so no-worry about connection polarity, either.

Rated 5 out of 5 by from Excellent quality connectorVery sturdy construction. Heavy-Duty case and terminals. Terminals make a very tight and heavy snap-action when making connection. Easy assembly. I'm using these connectors for jumper-booster cables on my truck (I'm a mobile mechanic). Instead of using conventional jumper cables, I'm using 2AWG wire and attached this connector to one end of the wire, and heavy-duty claws to the other end. Then, the second connector is permanently mounted to the side of my truck for easy access. Thus, attach the jumper cables claws/clamps to the disabled vehicle and plug the connector to my truck. No chance of short-circuit. Item is listed correctly as one unit piece, so you'll need to order a quantity of two if you plan to use it in a similar fashion.

Rated 5 out of 5 by from ExcellentThese are the exact same construction and sturdiness of any that you may have seen in use in any industrial application. A great way to remove DC power instantly.

Do you have a wiring diagram showing how this is connected to the power on the vehicle?

Asked by: jameson6
One lead is marked ( +) red, and the other is marked (-) black. two of these connectors interconnect to each other and generally connected directly to the battery.

Is it possible to panel mount one of these to allow a cable connectorized with another one to properly mate? I haven't seen any panel mount versions of this connector.

Asked by: W4ZQ
I am sorry, I am not aware of any panel mount versions of this connector.

what do these connectors mate with?

Asked by: younggene
These connectors mate with themselves. When you flip one 180 degrees, it will plug into another of the same type.
