6.1 Accuracy
The specifications are typical values for the BTL5-P… 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.

sea level.
3) Individual specifications as per Balluff factory standard
4) Resonant frequencies excluded
5) For : The BTL must be externally connected via a limited-energy
circuit as defined in UL 61010-1, a low-power source as defined in
UL 60950-1 or a class 2 power supply as defined in UL 1310 or
UL 1585.
