Fan Guard & Finger Grille (IEC 60950 / IEC 62368-1 finger probe) is used for keeping fingers and objects away from rotating fan blades in electronics, appliances and equipment while passing cooling air.
Also known as: metal fan guard, metal mesh finger guard, fan grille
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.
Materials
Standard supply is stainless steel 304; the material column in the table and the drawing options show the exact grade for each size. Other alloys and finishes can be quoted to your drawing.
Fitting & Care
Mount the guard with the fan screws so it is earthed through the chassis when metal.
Check the guard does not touch the blades under vibration.
Common Mistakes
Using a decorative grille that fails the finger-probe test.
Choosing a mounting pitch for the wrong fan size.
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.
Fan Guard & Finger Grille is made to order as finished parts. Indicative pricing starts from about US$0.35 per piece for a standard size at production quantity; the final price depends on size, material, finish, tooling and order volume.
