Plug/Connector Options

[Greg Dake]

Hi Everyone,

We have an application where we will be implementing a portable process pump cart. (7.5HP, 480V, centrifugal pump)

The portable pump cart will consist of pump/motor and a washdown rated VFD. I am looking for a plug option for the low voltage side for the VFD to bring in 4 conductors for the safe torque-off and the conductors required for Ethernet. I know Meltric makes good multi-pin connectors, but not sure about a good plug for the Ethernet connection. I really don't want to have three different plugs and trying to combine what I can. Just looking for options.

TIA,

Greg

The Harting modular connectors should be able to do it. I’m sure there are others out there, maybe try mencom or TE connectivity

If you don't need the disconnect function of the Meltric connector, I have used these for connecting 24VDC signals, Ethernet, and RS232 signals all in one connector.

They make connectors for this series that will handle 480VAC, but I would recommend against mixing 480VAC and low voltage or communication in the same connection.

The Harting connectors are what I see the most of in the food industry to connect portable equipment. Just be aware, they a major PIA to repair when they get wrecked. And it is just a matter of "when" not "if".
