Are the 2 items , 1 receiver and 1 sender?

Yes there is 1 receiver and 1 emitter

I need to replace two garage door sensors. Is this the sending or receiving sensor? Is this one pair of both receiving and sending sensor? Thanks.

it is a pair that includes both a sending and a receiving sensor, which is all you need. good luck.

How do you differentiate between the sending unit and the receiving unit?

It has it by the wiring coming in to the unit

Will these work with a Liftmaster 1046 that came with no sensors? I saw indication the "Model 70" sensor might work.

No they won't time to replace your opener
