What it is — and what it does
The Omron E2A-M30LS15-WP-B1 5M is a standard double distance sensing proximity switch from the E2A series. The part number tells you it's an M30-sized housing with a 5-meter cable, used for non-contact detection of metal targets in automated production lines, packaging machines, and conveyors. The double distance feature gives you extra sensing reach without a bigger body.
