It detects ferrous metal targets at up to 20 mm — double the range of a standard M30 shielded sensor. ## Output type and wiring This variant uses a DC 3-wire NPN normally-open output — the in the part number codes NPN NO. That means the output switches low (sinks to ground) when a target enters the sensing field. If your PLC or controller input expects a PNP sourcing signal, this sensor will not drive it directly; you would need a PNP version (e.g., E2A-M30KN20-WP-D1 2M).","metaTitle":"Omron E2A-M30KN20-WP-B1 2M Proximity Sensor, 20 mm Range","metaDescription":"Omron E2A-M30KN20-WP-B1 2M standard double-distance proximity sensor, M30 barrel, 20 mm sensing range, 2-meter cable.
