Design secondary part

The MCS consists of an u-shaped screwed steel base plate with adhered

permanent magnets. All fastening holes are in the fastening rail along the

secondary part.
To ensure a high corrosion protection , the iron parts of the secondary part

are nickel-plated and the permanent magnets are coated with epoxy.
