The XS630B3DAL2: It's a current-production part, so you're not hunting for NOS or surplus — it's still a standard catalog item from Schneider Electric. Inductive proximity sensors like this one detect the presence of metal targets without physical contact. They're common on conveyor lines, machine tooling, and packaging equipment where you need a non-contact position or limit signal.
Sourced to order against your BOM quantity.
Peer cross-reference check
Both are inductive sensors, but the XS9E111A2L2 carries a different UPC (389110355973) and may differ in sensing range, output type, or barrel size. Without a direct cross-reference from Schneider, you'd need to compare the datasheet specs side-by-side before swapping one for the other on a panel layout.
