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.

3)
Individual specifications as per Balluff factory standard, resonances
excluded
4)
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.
5)
A prerequisite is that no current can flow between GND and 0V in the
event of polarity reversal.
