Ferrite magnet
Cap magnet
Cap magnets are applied magnets that combine a ferrite magnet and a yoke (iron) to concentrate magnetic force in a certain direction, making it even stronger.It can be easily installed using the holes in the yoke (types without holes are also available).
Round type (R type)
Unit: mm
* Cap material is SPCC * Adsorption power is a reference value (measured with Imada digital force gauge)
surface treatment
1) Zinc plating/chromate treatment 2) Zinc plating/unichromate treatment

* Cap material is SPCC * Adsorption power is a reference value (measured with Imada digital force gauge)
* Since the magnetic flux is concentrated on the tip S of the cap, the suction force is 5 to 10 times that of the magnet alone.
