Construction and function (continued)
Examples on this page are only schematic
representations.
3.4.1 Pole-periodic magnetic tape
type BML-M...-R0000
(Not with BML-M0_-I5/6...)
The pole-periodic magnetic tape has alternating magnetic
south and north poles, but no integrated reference point.
The tape is suitable for sensors with or without
a pole-periodic reference signal.
Order example for the tape shown below:
BML-M03-I46-A0-M3500-R0000

3.4.2 Magnetic tape with single reference point
type BML-M...-R_ _ _ _ /0000
(Not with BML-M0_-I5/6...)
With a magnetic tape with single reference point, the
reference point can be integrated at any point. To
determine the exact absolute position, the reference run
must be performed over the tape to the reference point.
The tape is suitable for sensors with a single
reference signal.
Order example for the tape shown below:
BML-M02-I45-A0-M0100-R0040/0000

3.4.3 Magnetic tape with two reference points
type BML-M...-R_ _ _ _ /_ _ _ _
(Not with BML-M0_-I5/6...)
With a magnetic tape with two reference points, the
reference points can be integrated at any point. To
determine the exact absolute position, the reference run
must be performed over the entire length of the tape to the
external selection switch. The external selection switch
determines how the Z signals are used.

3.4.4 Magnetic tape with fixed-periodic reference
points type BML-M...-C0006/_ _ _ _
With magnetic tapes with fixed-periodic reference points,
the reference points are integrated over the entire length of
the tape at specific, uniform distances, e.g. every 20 cm.
To determine the exact position, the reference run must be
performed up to the external selection switch that
determines how the Z signals are used.
The tape is suitable for sensors with a single
reference signal.
Order example for the tape shown below:
BML-M02-I34-A0-M0100-C0006/0020
The first valid reference point is always 6 cm
from the start of the tape.

Function

When the incremental sensors in the sensor head move
over the magnetic tape, they sense the magnetic periods,
measure the magnetic alternating field, and transfer the
signals to the controller so it can detect the travel range.
