Technical data
11.1
Accuracy
The specifications are typical values for the BTL7-A/E... 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.
