10.1 Accuracy
The specifications are typical values for the
BTL7-A/C/E/G… at 24 V DC and room temperature, with
a nominal length of 500 mm in conjunction with the
BTL-P-1013-4R, BTL-P-1013-4S, BTL-P-1012-4R or
BTL-P-1014-2R magnet.
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.

Overvoltage protection Up to 36 V
1) Nominal length = 500 mm, magnet in the middle of the measuring range
2) Individual specifications as per Balluff factory standard
3) Resonant frequencies excluded
4) A prerequisite is that no current can flow between GND and 0 V in the
event of polarity reversal.
