1-TURN POTENTIOMETER - Meditronik

1-TURN POTENTIOMETER 

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

SAKAE 1-turn Potentiometers are fully continuous 

rotation potentiometers without stopper and are highly 

reliable in offering an excellent quality as well as a 

prolonged rotating life. There are 2 kinds of resistive 

element available in this series: Wirewound (CP) and 

Conductive Plastic (FCP-A) elements. You can easily 

make a best selection between these versions to your 

versatile application programs ranging from hand-operating 

use to servo applications. 

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) with 

performances and dimensions according to U.S. MIL, and 

V.R.C.I. Standards. They are light in weight and small in 

size 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 12mm 

and 50mm. 

THE NOMENCLATURE OF SAKAE 1-TURN POT. SERIES 

●Special Specifications 

S means the potentiometer with special mechanical 

specifications not applicable to our standard. 

●Type 

FCP means continuous, 1-turn, Iinear conductive plastic 

element type potentiometer. According to the kinds of 

resistive elements incorporated, there are 2 kinds: 

CP ..............Wirewound resistive element type (A is not 

given.) 

FCP-A ........Conductive plastic resistive element type. 

S FCP 30 A G - 

●4 digits branch number 

to be used for specific 

requirements. 

●Number of Gangs 

G means 2 ganged potentiometer on the 

same axle. The potentiometer consists of 

one single section unless G is given. (e.g. 

G3...3 ganged, G4...4 ganged) 

●Characteristics 

A means a conductive plastic resistive element type. 

(A is not given to wirewound type.) 

●Terminal Connection Diagram

●Diameter 

30 means approximate outer diameter of the 

potentiometer in metric system. The 6 standard 

diameters are available, namely, 12mm, 22mm, 30mm, 

40mm, 45mm and 50mm.

LOW-TORQUE POTENTIOMETER 

(Precision 1-turn, Low-torque, Wirewound Element) 

SAKAE Low-torque Potentiometers with a wirewound 

resistive element are very small in size and light in weight, 

It offers a very low starting torque of below 0.1mN•m 

(1gf•cm) in Model LNB22. Electrical detection of 

Wirewound 

MODEL LNB22 

(Precision 1-turn, Wirewound & Film Element) 

inclination, vibration, etc. is easily possible by installing 

these potentiometers on float, bellows, etc. These models 

are only available with wirewound resistive element as 

standard version. 

THE NOMENCLATURE OF SAKAE LOW TORQUE POT. 

●Special Specifications 

S means the potentiometer with special mechanical 

specifications not applicable to our standard. 

●Type 

LNB means 1-turn, low-torque, wirewound and Iinear potentiometer 

incorporated with precision miniature ball bearings. 

S LNB 22 G 


20 ±1 11.5 ±1 

- 

●4 digits branch number 

to be used for specific 

requirements. 

●Number of Gangs 

G means 2 ganged potentiometer on same axle. 

The potentiometer consists of one single section 

unless G is given. 

●Diameter 

22 means approximate outer diameter of the 

potentiometer in metric system.
