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
TEMPLATE Magnetic Tape AB20-80-10-1-R-D-15-BK80
Coding
absolute, single track system
Pole pitch

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:

Double-faced adhesive tape
3M-9088 (observe instructions), others on request
Dimensions
without adhesive tape:
10 mm (±0.1) x 1,35 mm (±0.11)
with adhesive tape (excl. carrier):
10 mm (±0.1) x 1,56 mm (±0.13)
with adhesive tape (incl. carrier):
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. 150 mm
Available lengths
up to 260 m
Weight 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 as this could damage or destroy the
code on the tape.
Protection class
IP65
