The E2E-X4B212-M1 is a shielded M12 barrel proximity switch — the shield concentrates the sensing field forward, so you can flush-mount it in metal without false triggers. 4 mm range is typical for a shielded M12; enough for tight spots where a target comes in close without needing a lot of standoff. Wired as a 3-wire DC PNP, normally closed. That means the output is high when no metal is present, and it switches low when the target enters the 4 mm window. Out here in the grease, that's handy for catching a part that's worked loose — if the wire breaks or the sensor fails, the signal drops and the controller sees it.

Frequently asked questions
Will a E2EC-CR5B1 drop in as a replacement?
The E2EC-CR5B1 is from the E2EC series, a different product line — not a direct functional equivalent for the E2E-X4B212-M1.
