7.1 Accuracy
The specifications are typical values for BTL7-C/E… at
24 V DC and room temperature, with a nominal length of
500 mm in conjunction with the BTL5-P-3800-2,
BTL5-P-4500-1, BTL5-P-5500-2

The transducer is fully operational immediately, with full
accuracy after warm-up.
For special versions, other technical data may
apply.
Special versions are indicated by the suffix -SA
on the part label.

In the position range from 0 to 20 mm, the specified linearity limit may be
exceeded by ±100 µm.

Only position output. For speed output, next-higher measured value rate
(500 µs or 750 µs).

4)
For : Use in enclosed spaces and up to a height of 2000 m above sea
level.
5)
Individual specifications as per Balluff factory standard
6)
Resonant frequencies excluded
7)
For : The transducer must be externally connected via a limited-
energy circuit as defined in UL 61010-1, a low-power source as defined in
UL 60950-1, or a class 2 power supply as defined in UL 1310 or
UL 1585.
8)
A prerequisite is that no current can flow between GND and 0 V in the
event of polarity reversal.
