TURNS-COUNTING DIAL
(for use with Helicalohm Pots. and Multi-turn Pots.)

Dial

SAKAE Turns-counting Dials are designed for use with
Helicalohm Potentiometers and multi-turn potentiometersand have an elegant appearance and rigid construction
offering an easy reading, smooth rotation and accurate
counting. There are a plenty of models: MA, MB, MF, MG
in analog type and DA, DB, DC in digital type. In particular,
MF and DB dials have a unique internal mechanism with a

special flexible coupling incorporated, which we developed(several patents obtained and designs registered) andadopted first of all in the world to solve the traditional
troubles such as irregular rotation and uneven torqueresulting from inaccurate mounting of the potentiometer ondial.

THE NOMENCLATURE OF SAKAE TURNS-COUNTING DIAL

SMB

10 - 25

B

6 - ○○○○○● 4 or 5 digits branch number
to be used for specificrequirements.

● Special Specifications
S means the turns-counting dial with special
mechanical specifications of graduation (Specialgraduation is available with only model MA.)

● Fitting Shaft Diameter
6 means the mounting hole of 6mm dia. to besuitable for the pot, with 6mm dia. shaft. The 5
standard mounting holes are available, namely,3mm, 3.175mm(model number:3.5), 4mm, 6mm
and 6.35mm(model number:6.5), but a single
model is not always furnished with all of these 5
sizes of holes. (Model MA has always 6mm dia.
hole and therefore, this indication is not necessary.)● TypeMB means a kind of model. The 7 models are MA, MB, MF,
MG, DA, DB and DC.

● Number of Turns
10 means 10 full turns-counting type. (The 6 standard
numbers of turns are available,) namely, 3, 5, 10, 15, 20 and100. It is convenient to use the dial with the same number ofturns as that of multi-turn potentiometer.

● LockB means that the lock lever is fitted to lock the dial rotation at
any desired position. No lock lever is fitted unless B is given.
● Diameter
25 means the approximate outer diameter of the dial body in metricsystem. (The 8 standard diameters are available,) namely, 15mm,22mm, 24mm, 25mm, 26mm, 27mm, 46mm and 55mm.

MA-55

You can read the number of turns-counting precisely in outer graduations which rotate
continuously relating to the shaft rotation without any intervals. Special graduations are available
in this series.

MB

MB-25

Popular sized dials with rigid construction for general use.

Most advanced dials in the world. Even the unskilled can easily mount it with the potentiometer on
the panel because this dial has a special flexible coupling inside, of which device is patented.
