6.4 Technical Data Magnetic Tape
The magnetic tape consists of two components:

The actual magnetic tape which carries the position information

A mechanical stainless steel back iron
Magnetic Tape MB20-50-10-1-R
Coding incremental, single track system
Pole pitch 5 mm
Operation temperature installed −20 … +65° C
Storage temperature uninstalled
Short-term: −10 … +60° C
Medium-term: 0 …+40° C
Long-term: +18° C
Gluing temperature: +18 … +30° C
Relative humidity max. 95 %, non-condensing
Accurateness 20°C in mm ±(25 + 20 x L), L = measuring length in meters

Double-faced adhesive tape 3M-9088 (observe instructions), others on request
Width 10 mm
Height magnetic tape without back iron stripe: 1.05 mm (± 0.10)
with back iron, without adhesive tape: 1.35 mm (± 0.11)
with back iron + adhesive tape, without protective foil: 1.55 mm (± 0.13)
with back iron + adhesive tape + protective foil: 1.63 mm (± 0.14)

Bending radius min. 150 mm
Available lengths 32 m (up to 70m on request)
Weight magnetic tape ca. 62 g/m (incl. magnetic tape and cover tape)
Tape imprint ELGO standard, printing color black, digit height >= 5 mm
Protection class IP65
Influence of external magnets
External magnetic fields must not exceed 64 mT (640 Oe; 52 kA/m) on
the surface of the magnetic tape because this could damage or destroy the
code on the tape.
