What the weld-field immunity means on a welding line
This is an Omron E2EW-X7D118-EV 2M, an M18 metal-faced inductive proximity sensor built to ignore the intense electromagnetic fields from resistance welding guns — the kind that burn out standard proxes in a shift. It gives equal sensing range on aluminum and iron targets, so a robot gripper handling mixed-material parts doesn't need two sensor types or a teach-in step.
M18 barrel — the mounting constraint
The M18 threaded barrel is the standard 18 mm diameter housing that fits common weld-field brackets and through-hole mounts. If your existing sensor bracket is M18, this drops in without rework. The 2-meter cable exit is fixed — no quick-disconnect option on this variant, so plan the cable routing before the weld slag zone.
Lifecycle reality — mature but not end-of-life
Listed as mature lifecycle stage — meaning Omron still produces it, but it's not a new-design push. For a BOM that will run another five years, this is fine. For a ten-year design, check whether the E2EW family has a successor planned — Omron typically flags that in the next revision cycle.
