Gefran PA1 Data Sheet
PA1
RECTILINEAR DISPLACEMENT TRANSDUCER
Principal characteristics
• The transducer’s compactness makes it suitable for
installation in small spaces and for detecting small shifts.
• The joint with up-take of slack and M4 threading provides
greater tolerances in movement.
• Installation is simplified by the lack of electrical signal
variation at output outside theoretical electrical stroke.
• Ideal for small mechanical devices, valves, and test tools
and benches.

INSTALLATION INSTRUCTIONS
• Respect the indicated electrical connections (DO NOT
use the transducer as a variable resistance)
• When calibrating the transducer, be careful to set the
stroke so that the output does not drop below 1% or rise
beyond 99% of the supply voltage.
