It uses an infrared LED and outputs NPN (Light-ON) via a connector, running on 12 to 24 VDC. If your BOM calls for a sinking sensor in a tight slot detection spot, this one fits without fuss.","metaTitle":"Omron EE-SPX403N Photomicrosensor, NPN, 13mm Slot","metaDescription":"Active through-beam photomicrosensor, NPN output, 13 mm slot width, 12-24 VDC, connector type.
