It's made by EBE a German company. You might have to try and contact them
through email for the exact replacement part.

Here's the Google translation of the webpage.

Why?

Probably trying to use it in an existing design. Parts like this seem to
vary pretty widely on mechanical layout.

Yes. Because of existing electrical interface & mechanical mounting. Could
re-engineer, but easiest / quickest is to replace with identical unit.

The electrical interfaces, at least of the models I've used, are identical.
Mounting varies somewhat across models, but it's close enough that a one-off
should be possible.
