Product description
The TTK70 non-contact linear encoder
consists of a compact read head and
a magnetic tape. The magnetic tape
is equipped with a magnetic partition
and forms the measurement scale. The
partition consists of an incremental and
an absolute track (two-track tape). To
calculate the absolute position value, the
At a glance
• Non-contact absolute positioning
• Small, compact read head
• Standard SSI interface, combined
with sin/cos output
Your benets
• Easy integration into existing systems
• Small size, low weight and high
traversing speed deliver excellent
process dynamics
• After installation, the system is
immediately available and completely
maintenance-free, which leads to time
and cost savings
read head detects both the absolute and
incremental components. The position
value is directly output for further processing.
The TTK70 has an SSI output for absolute positioning and an incremental Sin/
Cos output for recording speed in real
time.
• Measuring lengths of up to 4 m
possible
• High level of accuracy (± 10 µm)
• High resolution (1 µm)
• High traversing speed of up to 10 m/s
• Immune to environmental factors
such as contamination and condensation, ensuring increased reliability
• Real-time speed determination plus
absolute positioning due to Sin/Cos
and SSI output

The maximum permitted external eld inuence is reached when the position value deviates from the original value (without external eld inuence) by more than
5 μm. This value is reached when, at the sensor location, a eld strength of 3 kA/m to 4 kA/m (3.8 mT ... 5 mT) occurs in addition to the eld strength of the magnet-
ic tape.
