Gefran PK Data Sheet

PK

RODLESS RECTILINEAR DISPLACEMENT TRANSDUCER

Main features

• The transducer has been improved in order to guarantee
greater reliability under all conditions

• Mechanical linkage using joint with take up of play,
M5 thread

• Installation is made simpler by the absence of electri­cal signal variation in output, outside the Theoretical
Electrical Stroke

• The new grooves provide an excellent alternative to the
usual system of fastening with brackets

• Ideal for applications on plastic injection presses, vertical
presses, and on many other processing machines

• Grade of protection IP40

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.
