The Omron E2A-M12KS04-WP-B1 2M is a shielded M12 cylindrical proximity switch with standard double distance sensing, rated for 4 mm detection of ferrous targets. Output is PNP open collector on a 3-wire DC supply, with a pre-wired PVC cable.
How It Compares to the E2C-X1R5AH
The E2C-X1R5AH is an M8 heat-resistant head in a different series — smaller barrel (M8 vs M12), shorter sensing distance (1.5 mm vs 4 mm), and a 3-meter cable. These parts are not dimensionally or electrically interchangeable without panel rework; the E2A-M12KS04-WP-B1 2M is a larger, higher-sensitivity sensor suited to standard M12 mounting holes.
