HELICALOHM MULTI-TURN POTENTIOMETER

(Precision Multi-turn, Wirewound & Hybrid Element)

There are two kinds in SAKAE Helicalohm Potentiometers

with a wirewound resistive element. One is Model HD

Series which are an original device consisting of a resistive

element wound helically on a drum surface and a slider of

which contact is made around the resistance drum and the

other is Model HP Series which are formed with a slider

travelling along the interior surface of a resistive element

helically wound inside a sealed pipe.

Both of them equally offer high resolution, excellent

reliability and long life. SAKAE has expanded to the

production of hybrid resistive element potentiometers and

this element has now been incorporated into Model HP

Series with small size.

THE NOMENCLATURE OF SAKAE HELICALOHM POT. SERIES

Special Specifications

S means the potentiometer with special mechanical

specifications not applicable to our standard.

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.)

4 digits branch number

to be used for specific

requirements.

Number of Turns

10 means 10-turn. There are 5 kinds in the number of our standard

multi-turn potentiometers. They are 3, 5, 10, 15 and 20, but subject

to models.

Application

L means for semi-fixed purpose. P means for p.c. terminals. W

means for lug terminals at rear end. S means shortened body

type (only for use on 20HP-ns). E means inch dimensional

bushing and shaft type.

Mounting Method

S means servomount type(in case of bushingmount type, S is deleted.)

Diameter

46 means the approximate outer diameter of the poten-

tiometer in metric system. The 8 standard diameters are

available, namely, 10mm, 12mm, 20mm, 22mm, 25mm,

30mm, 46mm and 50mm.

Type and Internal Construction

H means helicalohm, multi-turn, linear potentiometer. There

are 4 kinds of HP, HHP, HD and HDS.

HP, HPC

.....

Wirewound type with resistive element helically

wound inside the pipe-shaped housing.

HHP

............

Hybrid type with same construction as HP type.

..............

Wirewound type with resistive element helically

wound on the drum-shaped base.

HDS

............

Super-precision type with same construction as

HD type.
