SAKAE MF dial is provided with a f lexible coupling situated between the shaftof the potentiometer to be mounted and inner dial knob. With such uniquedevice, traditional trouble such as irregular rotation and ununiform torque due toinaccurate mounting of the potentiometer on dial can be easily solved. Even theunskilled can mount this MF dial and you can save the labor cost using this MF
dial.

CAUTION: When rotating MF dial mounted with multi-turn potentiometer with over
0.2N・m force, the f lexible coupling may be damaged or broken. So,
please take care of this point during its operation.

Note1: The diameter of ※hole is depending on the diameter of potentiometer to be mounted.
Note2: When mounting the dial on potentiometer, the 2-f inger projections ( ＊ ) of mounting adaptor are inserted in the receiving holes
prepared on the base plate of dial f irmly, by adjusting the gap between 2-f inger projection ( ＊ ) with a screw-driver. There ispossibility where some irregular turns of dial may take place if the adjustment of this gap is insuf f icient.

How to mount MF Series

SPECIAL NUT FOR USE WITH MF DIALPOT.

MOUNTINGADAPTOR

DIAL

PANEL

The mounting adaptor as well as specially shaped nut
only for use with Model MF Series Dials and Helicalohm
pot. are f ixed on the panel according to the illustration
given the above.
The shaft of the Helicalohm pot. is turned anticlockwise
to its limit and is put into the mounting hole of thedial which is already set at "0" At the same time, 4

projections of the mounting adaptor are inserted in 4
receiving holes prepared on the base plate of the dialand then all parts should be pressed to the panel firmly
to eliminate any space. The shaft of the potentiometeris fixed by the hexagonal nut positioned in the knobof the dial by screwing it with an attached hexagonal
wrench. With this, the mounting is completed.
