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 MB20-20-10-1-R and MB20-50-10-1-R
Coding
incremental, single track system
Pole pitch
MB20-20-10-1-R: 2 mm
MB20-50-10-1-R: 5 mm
Operation temperature installed -20 … +65° C
(-20 … +80° C when using without adhesive tape, options „B“ or „D“)
Storage temperature uninstalled Short-term: -10 … +60° C
Medium-term: 0 …+40° C
Long-term: +18° C
(-20 … +80° C when using without adhesive tape, options „B“ or „D“)
Gluing temperature
+18 … +30° C
Relative humidity
max. 95 %, non-condensing
Accuracy at 20° C in µm
± (25 µm + 20 µm x L) L = measuring length in meters
Material carrier tape
precision strip 1.4310 / X10CrNi 18-8 (EN 10088-3)
Double-faced adhesive tape
3M-9088 (observe instructions), others on request
Dimensions
with carrier tape, without adhesive tape:
10 mm (± 0,1) x 1.35 mm (± 0.11)
with carrier tape + adhesive tape, without protection foil:
10 mm (± 0,1) x 1.56 mm (± 0.13)
with carrier tape + adhesive tape + protection foil:
10 mm (± 0,1) x 1.63 mm (± 0.14)
Length expansion coefficient
16 x 10
-6
1/K
Thermal length expansion
∆L[m] = L[m] x
[1/K] x ∆
[K]
(L = tape length in meters, ∆
= relative temperature change)
Bending radius
min. 60 mm
Available lengths
32 m (up to 70m on request)
Weight of the magnetic tape
ca. 62 g/m (incl. magnetic tape and cover tape)
Tape imprint
ELGO standard, printing color black, digit height >= 5 mm
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.
Protection class
IP65
