Nice one.

How about the other VTL5Cxx units? does your supplier also has boxes of those?

attached the different models

The box of parts was found in house.  So yeah that is a good chunk of assets  to liquidate.

Tube Town sells a 5C1 equivalent:

which is made/supplied  by Tesla whoever they are.

They also sell a Fender Vibrato LDR that looks an awful lot like what you are trying to build.

I think the other language in the Telsa data sheet is Serbo Croat. Croatia is in the EU,

Which is also in the EU. So how are they able to manufacture opto-resistors?

Making them is legit, so is using them as spare parts for existing (already-sold-to-end-user) products. And export too.

Ah, the wonders of EU legislation.

[Whoops]

So you can make them in EU

You can use in EU as spare parts in already sold units

You can export them

You can probably also sell them in EU

The only thing is that manufacturers of equipment are prohibited of using them in their commercial circuits?

Only if they then sell them in the EU. As far as I know they can  legally export them outside the EU.

Basically we can sell you our sh.t but you can't sell your sh.t here.

EU legislation?  Hmmmmm. So far from what I have experienced is as follows. we use the vtl5c1 as an opto cell in our compressor designs. The units are sold all over. We have yet to run into any problems with the EU other then France. For some reason France has taken it up a notch. Now this could be that we are grandfathered in as an existing design on the market but I am not sure. I have yet to get a straight answer from anyone who  may know. Sounds like typical government legislation.

 

[Whoops]

Who was the company producing the Vactrol or Vactec  VTL5Cx optocouplers?
Are they still in business?

Generally, the way the legislation works is you can do what you like until someone complains. There is no automatic checking that your product meets the declared standards. For example, nobody will check your product meets EMC requirements unless someone complains it interferes. Similarly nobody will check your design for prohibited substances unless someone (like the French) decides to complain. When you add a CE mark to your product you are declaring it meets the ROHS directive. If you attach the CE mark knowing your product does not meet the ROHS directive you have committed an offence and could be prosecuted, fined and even sent to gaol.
