Fan Guard & Finger Grille is used for keeping fingers and objects away from rotating fan blades in electronics, appliances and equipment while passing cooling air. IEC 62368-1 finger probe is the reference cited for it on drawings, datasheets and purchase orders.

The dimensions in the table below are supplied to suit IEC 62368-1 finger probe.

Specifying Fan Guard & Finger Grille Beyond the Standard
- Probe compliance: Hole size and standoff must pass the IEC finger probe for the product standard (e.g. IEC 62368-1).
- Fan size & screw pitch: Match the fan frame and mounting hole spacing exactly.
- Airflow: Perforated guards with high open area lose less airflow than wire guards of the same probe rating.
When Fan Guard & Finger Grille Is Not the Right Choice
Not a dust filter; add a filter pad or mesh if dust must be stopped.
