Penetrator Hole size for Drilling

[yvesyves]

Hi there, @EliotBR. Thanks for the immediate response.

@EliotBR

The M10 penetrators have an M10 external thread for mounting, which is 10 mm in diameter. A “10 mm through-hole” hole is recommended for whatever you are mounting the penetrator to. Note that “10 mm through-hole” is something you’re supposed to be able to pass something 10 mm wide through - our end caps use 10.2 mm holes.

Thanks for this clarification.

For the drilling diameters,

• the throat needs to be at least big enough to fit your wires through it, but small enough to avoid excessive weakening, and should be smaller than the cable jacket diameter
  • I’d recommend staying <8mm, but aim for ‘just’ big enough
• the shoulder needs to fit the cable jacket, with only a little bit of room to spare
• the head can be larger - just don’t get too close to the edges

For reference numbers you can measure the diameters on the provided CAD models against the suggested maximum cable diameters

Thanks for this. If I am following correctly, Blue Robotics does not specify exact hole diameters, but should however, follow these guidelines in drilling the penetrator holes?
