Gefran PZ12 Data Sheet
PZ12
RECTILINEAR DISPLACEMENT TRANSDUCER
WITH CYLINDRICAL CASE
Principal characteristics
• The 1/2” cylindrical housing, plus the option of all fastening systems (brackets, joints or flange), makes the
PZ12 series highly versatile for a wide range of applications.
• The optimized mechanical structure makes the product
suitable for developing various special executions (contact Gefran customer service for details).
• Installation is simplified by the lack of electrical signal
variation at output outside theoretical electrical stroke.
• Ideal for wood and glass working and finishing machines
and for car test 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.
