Photoelectric Sensor with linear spread
Photoelectric Sensor with linear spread
(OP)
I am looking for a simple photoelectric sensor/switch that detects over a line not a spot. It will be used to scan in between conveyor rollers and I need a scan length of 6-15". I don't want to go the light curtain route. Are these common? Any brands or I should I be looking into a different type of sensor? For some reason I can't find any.
Thanks,
Logan

Large size?
reflective material?
how fast the the conveyor moving? and what is the end goal of the sensor?

There are others.
Just get the catalogs and start reading; there has to be something appropriate.
You might search on 'line scan camera'.

There are also inexpensive forms of light curtains for such applications, as opposed to the ones used for safety. As sensors, the beams are more spread out and the safety functionality being removed makes them a lot more affordable for things like this.

RE: Photoelectric Sensor with linear spread
Unfortunately I cannot look at the side as I need to split the conveyor into 3 zones and that would only do 1. Also I must use diffuse as I cannot have anything below the conveyor, this pretty much voids non-safety light curatins.
I think what I will do is just chain together a bunch of photoelectric sensors and create my own array. It seems Automationdirect sells some for ~$40 or so and that is cheap enough.
Thanks everyone.
