2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Purpose
Magnetic switches are preferably used wherever mechanically operated
limit switches do not feature a satisfactory operation due to the
unfavourable operating conditions. In the elevator industry, magnetic
switches are preferably used for positioning and control purposes.
For actuating the magnetic swtches, the actuating magnets listed
by Schmersal (refer to Automation technology catalogue) can be
used. Depending on the chosen combination of magnetic switch and
actuating magnet, the switching distances and travels may vary.

3. Mounting
3.1 General mounting instructions
The installation may only be carried out by authorised
personnel.
• Any mounting position.
• Do not install the magnetic switch and the actuating magnet in strong
magnetic fields
• Keep away from metal chips
• Do not expose the magnetic switch and the actuating magnet to
strong vibrations and heavy shocks
• Do not use the magnetic switch and the actuating magnet as end stop
• The mounting distance between two sensors should always be at
least 30 mm.
When using more than one magnet switch, consider figures
