Laser sensor measure distance; Configure output to programmable logic

Hi Guys,

A Noob here. I'm trying to see if there's an existing solution out there that can solve this problem.

The objective is to count the amount of semiconductor device inside a tray.

Using a laser sensor, the output will be the distance between the laser and the unit at the end of the tray's lane.

The problem is, we have too many different sizes of devices that the distance for 1 case might not be the same for another case.

So we're looking at something like a selection of criteria before the measurement is done (i;e: the device type) and the output will be using the program/calculation formula of the selected device type.

Appreciate all the advice/comment/experience that you guys have on this. Thanks!
