8.1 Accuracy
The specifications are typical values for BTL7-S… at
24VDC, at room temperature, and with a nominal length
of 500mm in conjunction with the BTL-P-1013-4R,
BTL-P-1013-4S, BTL-P-1012-4R or BTL-P-1014-2R
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.
