I am completely re engineering our San Labs cleaner for better  
performance, i.e. it will go from bottom (dirty) to top (clean)  
instead of Top to bottom (anbody ever hear of gravity making junk  
fall?) so in my rebuilding of the drive logic I have decided to do  
away with the mechanical switch lever and replace it with an omron IR  
proximity sensor. Any thoughts on the slight IR beam? I assume that IR  
being used for dirt passes on scanners makes it safe or a non issue  
for cleaning film? Just looking for confirmation or any possible long  
term issues with using an IR sensor.
