6.3 Magnetic Tape MB20-25

The magnetic tape contains the necessary digital information needed for linear length measurement using an
ELGO length measuring systems. Basically a distinction is made between incremental and absolute measuring.
The incremental measuring system consists of reading electronic, which is scanning north and south poles on the
magnetic tape and is creating a Sine and Cosine signal.
These signals are electronically interpolated, the resolution of the measuring system results of the interpolation
rate and the pole length.

6.3.1 Components

In the standard case, the magnetic tape is delivered as described. It is installed by gluing it to the respective
mounting surface.
The magnetic tape consists of 2 pre-assembled components (see Figure 1):
A magnetized, flexible plastic tape (Pos. 3), which is connected with a magnetically conductive steel
tape as inference band (Pos. 4) and is supplied with an adhesive tape (Pos. 5).
A magnetized permeable cover tape (Pos. 1), which serves for the mechanical protection of the plastic
tape (not required for the measurement) and is supplied with an adhesive tape (Pos. 2).
Therefore a divergent tape structure and scope of delivery is also possible (see section 8.1).
The cover tape is also available separately (see section 11.3).
