Omron EE-SPX403N Photomicrosensor
Omron EE-SPX403N is a 13 mm broad-slot photomicrosensor that uses a 940 nm infrared LED to establish a fixed through-beam optical path. The sensing arrangement supports opaque targets down to 2.2 × 0.5 mm, while the stated differential distance is 0.05 mm maximum. Its NPN voltage output supports load currents up to 80 mA, and the unit operates from 12 to 24 VDC. Current consumption is specified at 15 mA maximum, while a special connector provides electrical integration. A red indicator supplies switching status, and the minimum response frequency is 100 Hz. Within the EE Series, the EE-SPX403N provides defined target passage within the 13 mm through-beam slot sensor range across Omron Precision Slot Sensors.

The Omron EE-SPX403N Photomicrosensor provides a 13 mm through-beam slot using a 940 nm pulse-lighting infrared LED. Opaque targets as small as 2.2 × 0.5 mm are specified, together with a differential distance of 0.05 mm maximum. Operating voltage is 12 to 24 VDC and current consumption is limited to 15 mA. The NPN voltage output supports up to 80 mA load current, while OFF current is 0.5 mA maximum. Residual voltage is specified at 2 V maximum with an 80 mA load and 1 V maximum at 10 mA. A special connector supplies the electrical interface, and a red indicator communicates switching status. Minimum response frequency is listed at 100 Hz.
For an Omron 13 mm broad-slot sensor requiring a compact NPN voltage-output arrangement, the relevant model is the EE-SPX403N. Its operating temperature range is -10 to 55°C, with storage from -25 to 65°C. Power-supply reverse-polarity and output reverse-polarity protection are included. The housing is polycarbonate and weighs approximately 4 g. Its wider opening provides more target clearance than the 3.6 mm slot versions, while the fixed internal optical geometry removes external emitter-to-receiver alignment. The supplied characteristics closely match the EE-SPX303N, giving a natural related option within the same broad-slot group. See EE-SPX303N for that related model.
