Grin Satiator - connection

[etienne.voice]

Recently bought a secondhand Grin Satiator, which made me happy because I'd been looking for a while. Mine came without the Singatron connector that fits onto the charger and ends in a Neutrix 3 pin XLR. After a bit of web browsing I bought this cable assy (technical document uploaded) and a bog standard Neutrix 3 pin XLR.
My question ( and I think I know the answer): When I solder the 3 pin assy to the XLR can I ignore the ground/shield on the supplied cable? The ground/shield does not need connecting to any of the pins in the XLR connector?

Appreciate your thoughts

I'm not exactly sure what you want to do here. If you're looking for a replacement Satiator DC output cable, Grin Tech sells one with XLR on one end and 3 pin Signatron on the other for $15 US. They are a Canadian company, so I imagine they would ship to the UK.

That Multicomp cable you linked appears to be 7 pins and will not fit the 3 pin on the Satiator.

In any case, I have 3 of the replacement Grin cables I linked above, Two have no cable shielding, but the third does. It is connected to the metal frame of the XLR, not any the pins. This tells me the shield isn't necessary since all 3 cables work fine.

That's what I think.

If the shielding isn't connected to something metal on both ends of the cable, then it isn't necessary.

The Hal sensors on my car (wheel speed sensor among others) need a shielding cable because the signal coming from those sensors is so miniscule that it gets drown out by ignition noise and lost on its way to the ECU if it isn't shielded.
