The data wheel on my H3000D/SX has become unresponding. According to
technote on Eventide site
http://www.eventide.com/technote/techn101.htm , this propably is due to
optical encoder gone bad.
I tried to vary resistor values as suggested on site, but it didn't help.
The part is obsolete, so
I thought I'd ask if anyone here happened to have a spare?

TIA,

A good tech could probably get this part to work if you can't find the exact
replacement.. Maybe that's what Eventide are suggesting when they say send
it to them.

Thank you Gareth, this is a valuable piece of information. The component
you found looks very
promising, it seems to operate on same voltage and looks just the same as
original at least.
I'll take a closer look at it!

Who makes it and what is the part number? Odds are you're going to have
to make a standard production Cherry or HP one fit in its place.

Yes, often you will find things like these and things like relays are kind
of generic in the sense that they do the same job with similar specs.
Sometimes the pinouts and/or mountings are different though, but often you
can get them to work with a little tweaking and/or re-wiring.


Good luck.

The part is manufactured by Sharp and its partnumber is GPIAI6R ('I' may
be '1' as well).
Yes, propably there is some creative engineering needed, or then I just
have to get used
to those push buttons

I will, but can't rush on this. These kind of interrupters seem to be
quite rare e.g. Digikey
carries none. The AEDS-962 you mentioned is my best bet this far.
Dimensions
and pinout are slightly different than in original Sharp GP1A16R

http://www.datasheets.org.uk/datashe...rticle=1563875

, but I think it is possible to
make it fit. I tried to find the original part from ic2ic.com, but there
seems to be only buyers
for this item

I tested the H3000 by manually grounding the data outputs of the encoder,
in order to produce
same kind of pulse that encoder should produce, and it worked. So the
fault must be in the encoder.
It might be as simple as dead LED emitter, maybe I should demolish my TV
remote?

BTW do you know any online store that carries AEDS-962 and would ship to
Finland? Farnell UK won't.

Oh, thanks, I should learn how to navigate I already ordered a
corresponding Sharp component,

will report on this later..

The optical interrupter/encoder Sharp GP1A038RBKLF arrived from DigiKey
and I soldered it into place. The pinout is totally different from the
original part, so I had to solder extension wire to every pin, result is
not excactly pretty
Mounting was nearly the same i.e. screws did fit and the code wheel fit
properly into the gap.

Happily the H3000 data wheel works perfect now. Thanks for advice!
