The impossible just happened.
I bought 100 Vastec 21L900 retroreflective switches for a stamp project,
googled for a spec sheet to get the lamp or led voltage. Got nothing!
Has anyone experience with this device?

anything I would expect documentation to be included. On the other hand, if
you bought them surplus / cheap you can afford to blow up a few trying to
figure out the hookup on your own.

Mfg is gone, parts are surplus, and I guess fireworks are in order.
Just thought someone might have used them.

number, I would say chances are slim that anyone around here has used this
sensor.

Hmmm, I found your request a little intriguing, so I did a
little digging. I couldn't find the datasheet for your part,
but may be able to help with a pointer or two.
One site in Google claims to have the 21L900 in their
inventory, and claimed the manufacturer was "EG&G".
This appears to be a company with *lots* of subsidiaries (as
an aside, it was founded by the inventor of the
strobelight). Among other things, they apparently worked on
the original triggers for the first nuclear weapons and now
do a ton of other government-related secret stuff. See:
http://www.abovetopsecret.com/pages/egg.html
They in turn have one subsidiary named "Vactec" (note: *NOT*
"Valtec") which apparently makes (made?) optoelectronics. I
suspect these may be the folks that made your part.
Continuing the hunt, it appears this division may have been
sold off to Perkins Elmer Opto, who I found at:
http://opto.perkinelmer.com/index.asp
Searching their site for 21L900 I couldn't find anything,
but I *did* find lots of references to other retroreflective
switches under the optoelectronics section, which seems to
confirm these to be the folks responsible for the desired
part. If you want some links to related to retroreflective
parts, try:
http://pki6.mondosearch.com/cgi-bin/MsmFind.exe?RESMASK=MssRes.msk&CFGNAME=MssFi\
nd.cfg&QUERY=retro&ct=optoelectronics
(if this link barfs because of line-wrapping or such, go to
the Perkins-Elmer site, navigate down to the Optoelectronics
page and do a search for "retro").
Among other things, they reference parts such as the
VTR16D1:

I don't know if any of this is actually related to your part
or not but it doesn't hurt to check it out. If nothing else
it gives yo a starting point for experimentation.
Good luck, and hope this helps...
