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 60950 is the reference cited for it on drawings, datasheets and purchase orders.
What IEC 60950 Means for Fan Guard & Finger Grille
The dimensions in the table below are supplied to suit IEC 60950. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.

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.
