Looking for thin sensor for detecting silicon wafers
Looking for thin sensor for detecting silicon wafers
(OP)
Hello, all. I'm looking for a very thin sensor that I can use for detecting silicon wafers. It is to be used in a robotic end-effector for the semiconductor industry.
I had previously planned on using a thin capacitive sensor which was to be offered by a certain vendor. Since then, I've been told that this sensor might not be offered after all, so I need to start looking for alternatives.
Help?

Where is it to be mounted? Barrell, bracket, tube?
What kind of environment? High temp? Wet?
What are you sensing? Presence, location, position, thickness?
What kind of signal? P-N-P, N-P-N, contact closure, analog?
Who have you already tried?
Love your handle by the way. From Lil' Abner right?

All other requirements (type of signal generated, etc) are flexible. We can always use adapter circuitry to modify the signal generated, for example.
