And that's being generous, as it seems that Nikon has kept a few older models still in production—perhaps to use up sensor commitments.
In terms of what Nikon currently sells as new, there are at least five different DX sensors in play, but strangely, not particularly differentiated. By consolidating sensor use in the lower end products and developing automated factories, they're tackling the broader consumer market with some prodigious cost cutting.
We've seen them back-track a bit with the 20mp sensor in the D7500 and D500, but you have to wonder what Nikon is doing here.
By my count, we have six different sensors in their ILC bodies (20mp 1", 20mp and 24mp DX, 20, 24, and 45mp FX).
Common rebar is made of unfinished tempered steel, making it susceptible to rusting.
Normally the concrete cover is able to provide a p H value higher than 12 avoiding the corrosion reaction.

is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and hold the concrete in tension.
Any material with sufficient tensile strength could potentially be used to reinforce concrete.
Sony, obviously, made a choice after NEX and SLT to back up and pursue high margin over volume, and they decided that meant that they had to be continuously vested in upping the sensor tech.
They've been first to a lot of things on the sensor side, but their camera prices had to go up in order to do that.
To prevent such a failure, rebar is either deeply embedded into adjacent structural members (40–60 times the diameter), or bent and hooked at the ends to lock it around the concrete and other rebar.
This first approach increases the friction locking the bar into place, while the second makes use of the high compressive strength of concrete.
This is similar to when Nikon fixated on repurposing the 6mp DX sensor across quite a few models. Canon is now in the position of making millions of basically the same sensor, potentially reducing their sensor costs both from an R&D standpoint as well as benefiting from yield improvements and a single inventory item to stock/track.
