Hi all,

I have a pair of ALPS RK168 type motorised potentiometer. Theyre dual gang and 10Kx2.
However I cannot find the pins functions.. Does anybody knows the pinout of that pots?

Thanks in advance.

Hi,
Do you have a multimeter to test for yourself?
Usually the middle pin (2) is the 'wiper' and the resistance between the 'wiper' and the other pins will change when you turn the pot.
Usually pins 1 and 3 are fixed at 10KOhm.

Obviously you will have two extra pins that power the motor.

All of my Alps pots are wired the same but this one has two extra 'Dummy' pins. (not in use.)

Datasheet

I found all of this information with Google "Alps Japan". 😉

However this pot has 8 pins. And there is no middle point.
And there is no data in datasheet..

Please look again!!

The picture (and datasheet) clearly shows the pin numbers.
Two of those pins are not connected (labelled 'Dummy').

THE TWO OUTSIDE PINS ARE NOT USED and the others are numbered on the picture.

The +ve & -ve are also clearly shown for the motor control

Usually, Pins '2' are the wipers.
Usually, pins 1 and 3 are fixed at 10KOhm.
You can check this with a resistance meter.

Martin.
