7 Technical Data
The following are typical values at DC 24 V and 25 °C. Fully operational after power-up, with full accuracy after
warm-up. Values are with BTL5-P-3800-2, BTL5-P-4500-1 or BTL5-P-5500-2 magnet held at a constant
offset from the transducer or with captive magnet BTL5-F/M/N-2814-1S (see magnet section for exceptions):
