[Résolu] Rambo Mini molex power connectors  

RE: Rambo Mini molex power connectors

I believe these are the Molex 3953x series or Eurostyle ESE3953x

Here's a link to one I found

A better option might be to solder heavy leadout wires to the board and get the connector and potential failure point away from the board.

Hello,

could anyone help me to identify the type of molex power connectors used on the Rambo Mini board? Connectors are damaged and partial melted for the years of service, I would like to resolder it for new ones. But can not find the exact type in the eshops, there are hundreds of them. And Prusa support also does not know.

I believe somebody from the proud MK2x owners must have done it too before 🙂

Thank you.

Thank you both for your help. The exact part number is 39531-0004.

These connectors are the weak point of MK2, that is true. But it served 5 years, so will give it one more chance 😉
