The closest sibling in the same family is the E2B-S08LS01-MC-C1, which shares the shielded 8 mm form factor, M8 connector, and NPN output, but uses a long barrel and a normally open output rated at 1.5 mm. If you have a panel wired for an NC sensor with a short barrel, the E2B-S08KS02-MC-C2 is the direct fit — the long-barrel version would require a different mounting depth. The normally open / normally closed difference is a wiring decision, not a mechanical one, so the existing cable can be repinned if necessary.
The 8 mm diameter stainless steel barrel has a short body and M8 connector. Shielded design permits flush mounting in metal.
