Magnetic track length

Conventional calculation
7.1.1
Version: 1.7
This chapter contains information on determining the length of the
magnetic track. The necessary travel range is determined by the ap-
plication specifications.
The required magnetic path length corresponds to the travel range
including the length of the coil part used.
During the planning phase it is necessary to determine the number
of magnetic plates required.
Two options are available for determining the number of magnetic
plates required:
• conventional calculation and
• effective calculation.
Both approaches calculate a minimum requirement. In practice, the
magnetic tracks are longer, since the space for limit switches and
reserves is included in the calculation. In addition, whole magnetic
plates are always used.
In a conventional calculation, the length of the coil part is added to
the travel path of the application and then divided by the length of
the magnetic plate.
Example for conventional calculation:
Travel path = 490 mm
Length of coil part AL8041 = 93 mm
Length of magnetic plate AL8542 = 288 mm
Required number of magnetic plates:
(490 mm + 93 mm)/288 = 2.02 magnetic plates < 3 magnetic plates
are required
