Hazardous-area inductive sensor — what it is
The XS630B1PAL2EX is a Telemecanique-branded inductive proximity sensor from Schneider Electric, specifically listed for hazardous-area duty. That means it carries the approvals and construction needed inside a Zone-classified environment — not a standard M30 barrel swapped in. The sensing face and housing are built to prevent an ignition source from escaping, so you can mount it where a conventional sensor would need an isolating interface.
Sourcing and fit — what to confirm
The order code XS630B1PAL2EX is the full part number — no suffix variation. M30 barrel, PNP output, NO contact, 2-wire or 3-wire depending on the variant. The hazardous-area listing is the deciding factor: if your spec calls for a standard industrial inductive sensor, a non-hazardous-rated sibling like the XS608B1DBL2 may fit at a lower cost, but it will not carry the area classification. Confirm the sensing range and output type against your PLC input card before committing the line item.
