What this sensor is and why it matters for the BOM line
The Omron E2E-X18MC130 2M from the E2E NEXT series is a current-production M30 unshielded inductive proximity sensor with an 18 mm sensing range, NPN normally-open output, and a 200 mA load rating on 10-30V DC. That 18 mm gap, combined with the unshielded face, means it detects ferrous targets at a longer distance than a shielded version of the same diameter—handy when you need clearance behind the sensor or a gap that reaches through a bracket hole. The output is a simple three-wire NPN sinking configuration, so it pulls low when a target enters the field; check that your PLC input module is sourcing (PNP) if you plan to swap this in, because this is a sinking (NPN) device.
Mounting and environment—what the ratings mean on the floor
Body is nickel-plated brass with a 30 mm diameter thread (M30). That's a standard metric thread that fits most M30 weld-on brackets or through-hole mounts. The 2-meter prewired cable comes with bare wires, so you land it directly in a terminal block or M12 pigtail junction. Goes without saying (but I'll say it anyway): the unshielded face means some metal around the barrel can affect the detection zone—leave a few millimeters of free space around the sensing face, and don't mount it flush in a steel panel. For washdown zones, the IP67G and IP69K ratings are the real story: IP67G adds oil resistance to the basic submersion rating, and IP69K handles high-pressure, high-temperature sprays common in food processing. That, plus the oil-resistant cable jacket and Prox3 hybrid circuitry with thermal distance control, make this a strong choice for packaging, automotive machining, or any line where coolant and washdown are daily.
Compliance documentation
The sensor is certified to CE, CSA C22.2, and UL 60947-5-2 (editions 4 and 14).
