7.1 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 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.

1) Nominal length = 500 mm, magnet in the center of the measuring range
2)
For UL: Use in enclosed spaces and up to a height of 2000 m above sea
level.
3)
Individual specifications as per Balluff factory standard
4)
Resonant frequencies excluded
5) Nominal length > 2000 mm: use only under static conditions
6)
For UL: The BTL 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.
7)
A prerequisite is that no current can flow between GND and 0 V in the
event of polarity reversal.
