7.1 Accuracy
The specifications are typical values for BTL7-C/E… at
24VDC and room temperature, with a nominal length of
500mm in conjunction with the BTL5-P-3800-2,
BTL5-P-4500-1, BTL5-P-5500-21), BTL6-A-3800-21),
BTL6-A-3801-21), BTL5-F-2814-1S, BTL5-T-2814-1S,
BTL5-M-2814-1S or BTL5-N-2814-1S 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.

1) In the position range from 0 to 20 mm, the specified linearity limit may be
exceeded by ±100 µm.
2) Only position output. For speed output, next-higher measured value rate
(500µs or 750µs).
3) Nominal length 500mm, magnet in the middle of the measuring range
4) For : Use in enclosed spaces and up to a height of 2000m above sea
level.
5) Individual specifications as per Balluff factory standard
6) Resonant frequencies excluded
7) For : The transducer must be externally connected via a limited-
energy circuit as defined in UL61010-1, a low-power source as defined in
UL60950-1, or a class2 power supply as defined in UL1310 or
UL1585.
8) A prerequisite is that no current can flow between GND and 0 V in the
event of polarity reversal.
9) Only with PC software (Micropulse Configuration Tool)
