Hi all,
I just salvaged an old sony music system & found quite a few parts that I cannot recognise. This one in particular was used for valine control but unlike regular potentiometer it has no start or end. Imaged of the part are attached.
Thanks.

 

Does it click like a switch when you turn it all the way to the left? I suspect the two terminals at the side are a switch and the three in front are the normal three terminals on a pot.

 

Hi B REEVES,
It has no start or end. Just rotates in either direction endlessly.

 

It sounds like it may be some sort of rotary encoder. See if the three terminal lugs act as switches.

A computer/controller can translate these closures into rotation commands for "going up" or "going down."

 

The component you have is a rotary encoder.....used in quite a few different models mainly as a volume control

 

Thanks for the information.
So I won't be able to use it without an encoder. As I understand.. its just a rotator switch , right ?

 

There is another component - KDS9J. Looks like a crystal oscillator but not able to confirm it.

Thanks.

PS: I have taken the essential part from the picture.

 

Also another one : 182J. Unable to identify it.

Hello,

I have edited the pictures to show the essential part of the pictures.
I have used a paint-like program to do this.

The first part is a crystal, not knowing its freqrency.
The second part is a capacitor of 1800 pF.

Thanks beruts.
