Area Sensors

Q-1
What if I want to use area sensors to detect the passing of thick objects?
Q-2
I would like to discriminate the sizes of the passing objects. Is there an area sensor where individual beam output is possible?
Q-3
Can I mute the sensor (muting) by using the emission halt function of the NA2-N series?
Q-4
I would like to use a PLC to make the job indicator of NA2-N series blink. Is such external control possible?
Q-5
With NA2-N series, I would like to have both the job indicators for receiver and emitter to light up at the same time as the sensor output. Please teach me on how to setup the wiring.
Q-6
I would like to mount original protection cover on NA2-N series. When making a hole for beam channel on both emitter and receiver surfaces, is a hole of dia. 20mm big enough?
Q-7
How do I prevent interference when having 3 sets of area sensors NA40 series connected in an U-shaped series connection?
