What are the installation hole diameters required for the panel-mounted M9 socket?

Mounting Hole Size Requirements for Panel Mount M9 Sockets

Standard Installation Parameters

Mounting Hole Diameter : Standard panel mount M9 sockets are adapted to 9.5~10mm mounting hole diameter, which is the industry-universal size specification.
Recommended Panel Thickness : The optimal panel thickness is 1~3mm to ensure the locking nut can be fully tightened and the sealing performance is up to standard.

Special Installation Scenarios & Customization Solutions

Non-standard Panel Thickness

If the panel thickness is too thick or too thin (beyond 1~3mm), customized extended locking nuts are required to ensure stable installation and reliable sealing.

Non-standard Hole Diameter Adaptation

Some manufacturers provide non-standard hole diameter adaptation solutions, which can be customized according to the actual panel hole size of the equipment to meet personalized installation needs.

Technical Note: The 9.5~10mm mounting hole diameter is the optimal size to balance installation stability and sealing performance; non-standard customization will increase the delivery cycle and cost, it is recommended to use standard size as much as possible.
