Erwin Sick Australia have the Stegmann range. The AFS60 range are 18 bit

Have used them in the past, and they have an easy to use RS422/485 or

This encoder can be used to accurately check the vertical position of a
slice of bread in a pop-up toaster.
This method of toasting is excellent. As the bread dries out it shrinks,
with the aid of servo motors the slice of bread/toast can then be adjusted
to the correct position to obtain the best possible toast.
Phil is therefore quite correct - 18 bit resolution is a bit of an overkill
for this application, probably a 16-17 bit would suffice.
Having said that, maybe Phil is busy designing a new range of toasters and
wants to keep it hush-hush. I'm sure he is going to surprise us with a
super-dooper model using 5 servos and two 22 bit absolute rotary encoders
with a latitudinal and vertical take-off with differential correction
adjustable via a slot in the second element, unless he deploys three or more
elements to control the browning more evenly.
I await his new offering with great excitement.
Rumour also has it that his new toaster will be compatible with Facebook and
Twitter plus a whole host of other goodies.
It is possible though, that his first versions will only be available for
use with Windows. The Linux models will probably follow when the Kernal gets
transferred to Timbucktoo.

Spoke to a Sick Stegman rep the other day, He said the AFS60 was so new
they didn't even have an Australian price for it let alone a unit in the
country and then emailed me a price.
The price goes up every time I phone or email them. Maybe there is a
wide price variation between variants in the family.

Sorry, I actually meant I had used the Stegmann range before (not

Thanks David, while I've got you here, do you have any experience with
Hengstler or IVO encoders?, they have some nice units that may do the
trick in their online catalogues but I've never personally used them
before or even know if they are available/affordable.
