NON-LINEAR POTENTIOMETER(Precision 1-turn, Wirewound & Conductive Plastic Element)

Non-linear

A precise detection of Sine-Cosine function voltage can beobtained through the shaft revolution of SAKAE NonLinear Potentiometer Series. There are 2 kinds ofresistive element in this series: traditional wirewound withhigh stability and latest conductive plastic featuring long life
expectancy and high speed tracking ability.

THE NOMENCLATURE OF SAKAE NON-LINEAR POT. SERIESSFSCB30

A

G - ○○○○○● 4 or 5 digits branch numberto be used for specific requirements.

● Special SpecificationsS means the potentiometer with special mechanical specifications.

● Number of Gangs
G means 2 ganged potentiometer on thesame axle. The potentiometer consists ofone single section unless G is given.
(e.g. G3...3 ganged, G4...4 ganged.)● TypeFSCB means a conductive plastic type potentiometer withcontinuous, sine-cosine function.

● Characteristics
A means a conductive plastic resistive element type.

● Diameter
30 means approximate outer diameter of the potentiometer in metric system. The 3 standard diameters areavailable, namely, 22mm, 30mm and 50mm.

Note: 2. 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.
3. 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.)
4. All values of each parameter were measured under standard temperature and standard testing conditions. For the values during the tests and other characteristics,
please ask us separately.
