The E2A-M12LS04-WP-B2: M12 barrel, 56 mm body, PNP normally closed output. Senses 4 mm into ferrous metal targets. Supply tolerant from 12 to 24 V DC with 200 mA max load. Cable exit is axial, 2 m, unshielded. Temperature floor at -40 °C — odd for an inductive, but it's real.
Threaded M12 barrel accepts standard mounting nuts (not included). Cable is 2 m, pre-wired; no connector means a direct swap requires cutting and re-terminating. Keep cable away from high-frequency drives — no shielding, so pick a clean wireway.
