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 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.
