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 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.

Overvoltage protection Up to 36 V
1)
Nominal length 500 mm, magnet in the middle 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)
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.
6)
A prerequisite is that no current can flow between GND and 0 V in the
event of polarity reversal.
