Default Sensor that detect slim thin part?

Hi there,
I have a conveyor that deliver the following kitchen parts such as:
Stove pan ring

or this without the handle:
Shape patters

What is the best kind of sensor to detect?
I was thinking some inductive sensor that look from the top, but unfortunately the conveyor is pretty wide, so a round inductive sensor doesn't cut it. Where it sometimes will see the side, or sometimes it count as 2, or doesnt see anything at all.

Is there any inductive sensor that is horizontal?

The other way might be using a light curtain to detect when the part drop. But, what if it drop in between the light curtain beams..

Vision will be one, but it cost too much.

Opinions are greatly appreciated.

How fast is the conveyor moving? How many parts per minute are you anticipating?

Not a lot of info to go by here, but a simple infared beam with a reflector, similar to a garage door detector would work for a horizontal read and counter.

You could set it up so that the beam is just high enough off of the belt to be broken by the product.
Or, have your product bar coded before it goes onto the conveyor and invest in a SICK reader.
