At a glance – what this sensor is for
The Omron E2B-S08KS01-MC-B1 is a shielded 8 mm cylindrical inductive proximity sensor from the E2B series. It's a normally open PNP device with a 1.5 mm sensing distance, terminated with an M8 connector. The shielded design means you can flush-mount it into metal without the standoff gap an unshielded sensor would need – handy when panel space is tight. The stainless steel housing and short barrel keep it durable and compact, sized for 8 mm mounting holes. Output is PNP, so it pairs directly with most modern PLC sinking inputs – no pull-up resistor needed.
What the key specs mean for your panel
Sensing distance of 1.5 mm is the factory-set standard sensing range – it'll detect a ferrous target (like iron or steel) at that distance. Shielded construction lets you embed the face in metal, but the sensor will only see targets in front; side interaction is blocked. M8 connector allows use of a pre-made cable for quick wiring and replacement.
If your panel was originally built around an E2C-X1R5AH, don't assume the E2B-S08KS01-MC-B1 drops straight in. The E2C uses a pre-wired cable (3 m) while this E2B has an M8 connector – so you'll need to either re-terminate or swap the cable assembly. The E2C also has a wider temperature range (-10 to 200 °C) and a brass housing, versus the E2B's stainless steel. For most standard machine environments the E2B will work fine, but if the application sees high heat or needs the original E2C's heat-resistance rating, stick with that series.
