How to make a conveyor (electric part)
Selection components to control a 3 phase motor/conveyer


The components you selected are adequate for the load you specify. 

The Schneider lc1d09 contactor has adequate load capability. I would strongly suggest that you use the 24V AC coil (or the 110V AC coil) to ease your wiring since you appear not to be using a DIN enclosure. 

To drive the contactor you will need a Class 105/106 rated control transformer.
Here is an example that might be suitable for phase to neutral connection:



This allows your wiring closet to be only AC mains equipment. 

To setup your optical curtain you need to select a device of course, and should get a floating relay output for either 24 or 120V AC rating (most will easily do this. This will probably be a low voltage 12 or 24V DC operation and kept separate from your motor wiring.
