Alps Potentiometer

[Nikon1975]

Dear All,

Can you help me identify this potentiometer ? It is an APLS PCB 10mm, with a value of 20kOhm. What I do not understand is why it has 5 pins.

It comes from a Zoom RhythmTrak RT-223.

Regards,

Davide

use a multimeter to measure resistance between the pins. Some of those pins could be just for mounting on a PCB

Use the ALPS part number printed on the pot to find out what the pin out is.
Just google the part number.

OK, there is no part number I could find even with the microscope.

And I read the value with the multimeter, but I do not understand the 5 pins. These are not mounting pins.

If it is a tandem pot it is probably two wipers, two feeds and one common.
I would say it was 9mm not 10mm which means RK09K12A0A2K is the model series.

Perfect thanks. I had never seen such part.

One other possibility. Some pots like that have push switches. For some function you rotate the knob then push in momentarily. Those pins could be from the inner tactile switch.
