Disc-type holding magnets (with central hole)

with barium ferrite magnets
In comparison to the disc-type holding magnets opposite these holding magnets have a central hole. As a result the holding magnets can be economically attached to a surface using countersunk-head or fillister-head screws.
PRODUCT DESCRIPTION

For fixing, only countersunk-head screws made from nonmagnetic, non-conducting material (e.g. stainless steel, brass) may be used for model A.

Holding force decrease:  - 4% per + 10 °C reversible
Reference temperature: + 20 °C
Encasing surface:  zinc plated

All dimensions in mm.

* The holding forces were measured on a ground sheet made of mild steel with a thickness of 10 mm with vertical drawing power. The values given are typical values and can be undershot or exceeded slightly. Small hairline cracks in the magnetic material do not affect the holding force. Ceramic magnetic material is non-corrosive and can be used in wet areas. The shifting force is between 20 - 35% of the holding force, depending on the state of the surface.
