Technical data
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
1) Individual specifications as per Balluff factory standard
2) 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.
3) A prerequisite is that no current can flow between GND and 0 V in the
event of polarity reversal.
