Hi all again! This evening I am just sitting around and working. I keep looking up at this part that has been sitting around on my desktop for at least the last 2 years, maybe more. I wonder what it is!
It appears to be a photo-resistive device- I say this because it slightly resembles one structurally. As well, I've tried a few resistance measurements and it does appear to change when I cover the sensing area.
The package itself it what confuses me! It looks like the contact portion of a mass produced button (the contacting membrane I guess) and is laid out on what appears to be ceramic. The ceramic is then also laid onto a steel slug, like a sink almost,, although I suspect it is for mounting rather than diss. 2 leads, and thats about all there is to it. I'm still confused. Anyone familiar with these types of devices- is there any info somewhere I can check out?
any help= much thanks; jd
