On the hunt for some 60mm faders

Parts Questions
1

So as per the other thread in here, I am tracking down some new 60mm faders. I had a look on Farnell (seems to be the easiest electronics site to navigate!) and came up with a HELL of alot of results.

I found 5 different 60mm 10k ohm panasonic faders…all similar price…but I have no idea what their real differences are? Also, I can’t see if it is mentioned whether they are linear or log? im sure it is…but not in language I can understand (ie. I don’t speak smart electronics talk).

The one thing I did notice between them all is they obviously have different power ratings. Is there any specific desired power rating for midibox64s? or just the less the better?

here they are:

any advice greatly appreciated :slight_smile:

Open a datasheet. In the middle of the 1st page you can find the “Explanation of Part Numbers”

  • Digits 1-3: ProductCode = fix (it’s this type of fader / housing /physical built)
  • Digits 4-6: Specification - Q = 60mm type, 1 = single taper (see 2nd page - drawings)
  • Digits 7-9: LeverTrims & Dimensions - I think there is only one type available (see drawing)
  • Digits 10-12: Taper & Resistance - I think “B” is linear

So you probably want: EWAQ12C15B14

http://www.panasonic.com/industrial/components/pdf/AOL0000PE1.pdf Going by this document it would appear as though type b is the linear one yea…even though it labels H/BH as the linear type (Albeit “special”…how cryptic)
