11.1 Accuracy
The specifications are typical values for 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 BTL 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.

For
: Use in enclosed spaces and up to a height of 2000 m above sea
level.
3)
Individual specifications as per Balluff factory standard
4)
For
: The transducer must be externally connected via a limitedenergy
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.
