Absolute tapes

Absolute tapes consist of multiple tracks. One of these is
the incremental track.
With PRC tapes an additional PRC track (see
section 3.5.1) is applied to the tape.
With nonius tapes (see section 3.5.2) there may be up to
two additional tracks on the tape.
The coding of sensor head and tape must be compatible.

3.5.1

PRC coding E and L

These tapes consist of an incremental track with a pole
width of 2 mm and a PRC track with a pole width of 2 mm
(E coding) or 4 mm (L coding).
Measuring length 1) Coding
≤ 48 m ABS PRC E
≤ 8.19 m ABS PRC L
1) For actual measuring length values see section 7 (see tables on
page 19 and 21)
Tab. 3-3: PRC coding E and L
3.5.2 NON coding A, C and F
This tape consists of an incremental track with a pole
width of 1 mm and two tracks with a somewhat greater
pole width (nonius).
Three different lengths each with their own coding are
available.
Measuring length 1) Coding
≤ 64 mm ABS NON A
≤ 256 mm ABS NON C
≤ 997 mm ABS NON F
