I'm tryng to select a Bulgin Buccanneer power connector, and the panel-mounted ones come in "Front Panel" and "Rear Panel" varieties. Why is there a distinction?
I'm struggling, because I need a connector to fit on a panel that's on the side...!
This is a case of "does it mount to the panel from the inside (Rear) or outside (Front)?", not "is the panel on the front or rear of the box"!
The rear panel-mount part installs from inside the box and has the jam nut on the outside of the case; the front panel one installs from the outside of the box and has the jam nut on the inside... It is that simple.
Bulgin has uploaded a video demonstrating the difference between the two types - Rear vs Front Panel Mount Connectors
Hope that helps!
