The Omron E2B-S08LS01-MC-B1 is a shielded inductive proximity switch from the E2B series. It's the PNP normally-open variant with a 1.5 mm sensing distance, an M8 connector, and a long-body 8 mm diameter stainless steel housing.
How it sits against a real sibling
The E2B-S08LS01-MC-C1 is the exact same sensor except it outputs NPN. If your BOM or panel was wired for NPN (sinking), this MC-B1 won't trigger your input without a wiring change or a converter. Everything else — shielding, range, connector, body dimensions — is identical between the two. The short-body cable version E2B-S08KS02-WP-B1 5M trades the long barrel for a 2 mm sensing range and a 5-meter PVC cable; it's not a direct mechanical swap for a bracket designed around a long body.
