1-TURN CONTACT POTENTIOMETER(Precision 1-turn, Wirewound & Conductive Plastic Element)▼1-Turn

CP or FCP-A is respectively contained in an aluminum
housing case processed by electrolytic corrosion-proof
plating in silver color (CP) and black color (FCP-A) withperformances and dimensions according to U.S. MIL, andV.R.C.I. Standards. They are light in weight and small insize as well as of rigid construction. Selection of any
desired item is possible among a variety of standard
models, of which diameters are variable between 12mmand 50mm.

Contact type

SAKAE 1-turn, contact Potentiometers are fully continuous
rotation potentiometers without stopper and are highly
reliable in offering an excellent quality as well as aprolonged rotating life. There are 2 kinds of resistive
element available in this series: Wirewound (CP) andConductive Plastic (FCP-A) elements. You can easily
make a best selection between these versions to yourversatile application programs ranging from hand-operating
use to servo applications.

Rotational LifeExpectancy(at 25℃ )｝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 withinstandard 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.
