LINEAR-MOTION POTENTIOMETER(Precision Linear-motion, Wirewound, Conductive Plastic & Hybrid Element)▼Linear-motion

SAKAE Linear-motion Potentiometers are compact insize and light in weight and are capable of transforming
mechan­ic­ al linear movements into corresponding electricalvariations. Easy to operate and handy. It is suitable formea­­sure­ment of linear movements in various machineryand tools and dis­placements in linearly moving objects
such as steer­­ing angles, numerical control toolingmachines, robots, etc.
Beside wirewound type (LP), there is another kind of resis­­tive element in this series: Conductive Plastic (FLP-A)
which features high resolution, long life expectancy andexcel­lent high speed tracking ability. Please select theresis­tive element appropriately according to your appli­ca­tions.

Note: 4. In the case of the potentiometer with special resistance values and special specifications, the above performances may vary and therefore, please consult us in advance,separately.
5. As for operating temperature range, we can’t always guarantee exactly the same performances and values in actual industrial applications even if the temperature out there
is within standard range. (Please see page 23 in this catalog for further details.)
6. All values of each parameter were measured under standard temperature and standard testing conditions. For the values during the tests and other characteristics, pleaseask us separately.

※N.B:Model 18 FLP series with spring return device and sealed version under IP54 have theoperating temperature range of 0℃ to + 60℃.
