2.6 Installation of magnetic sensor and magnetic strip
INFORMATION
An active reading head is necessary in order to use magnetic strips with the DPA22.
Item no. 338 3934
TTL differential signal pinout
Installation may only be carried out in accordance with the specified IP protection. If necessary
the system must be protected against environmental influences, such as Sprayed water, sol-
vent, dust, shocks, vibrations, temperature fluctuations.
The mounting surface / measuring track must be flat. Buckles or bumps will lead to measuring
inaccuracies.
For technical reasons the strip should be approx. 30mm longer than the actual measuring dis-
tance.
ATTENTION!
For an optimum of adhesion, all anti-adhesive substances (such as oil, grease, dust etc.)
must be removed by using residue-free (=evaporating) cleaners. Suitable cleansing
agents are e.g. ketones (acetone) or alcohols; Messrs.octite and 3M can both supply
such cleansing liquid. Make sure that the surface to be glued is dry and apply the stop
with maximum pressure. Glueing should preferably be undertaken at temperatures
between 20° to 30° Celsius and in dry atmosphere.
INFORMATION
When applying long pieces of magnetic strip do not immediately remove the complete protec-
tive foil, but rather peel back a short part from the end sufficient to fix the strip. Now align the
strip. As the protective strip is then peeled back and out press the tape firmly onto the mount-
ing surface. (a wallpaper roller wheel could be used to assist in applying pressure onto the
magnetic strip when fixing it in position)
