E2E-X20MC3L18-R 2M is a long-body M18 unshielded proximity sensor from Omron's E2E NEXT series. It switches at 20 mm on ferrous metal with NPN complementary outputs (NO+NC) at 10–30 VDC. The triple IP rating—IP67, IP67G, IP69K—means this sensor survives washdown and high-pressure spray. Nickel-plated brass housing, PBT sensing face. 2 m PVC robot cable.
This is an active Omron catalog number, not a special. If the BOM line needs this exact NPN complement output, it's the right pick—no substitution needed.
