Omron EE-SPX401 Photomicrosensor
Omron EE-SPX401 is a Light-ON slot photomicrosensor designed around a fixed 3.6 mm through-beam sensing distance. Its modulated optical path extends across the slot, allowing an entering target to change the NPN output state at a defined machine position. The sensor operates from 5 to 24 VDC and connects through a special connector. Average current consumption is specified at 15 mA maximum, with a peak value of 50 mA, while the output supports up to 80 mA load current. A red indicator provides visual switching information during operation. The short slot width supports compact sensing arrangements where target travel is tightly controlled. The EE-SPX401 provides Light-ON switching within the compact slot photomicrosensor range across Omron Precision Optical Sensors.

The Omron EE-SPX401 Photomicrosensor uses modulated through-beam sensing across a fixed 3.6 mm slot and operates with Light-ON switching. A target entering the slot changes the optical condition and the NPN output state communicated to compatible control circuitry. Operating voltage is 5 to 24 VDC. Average current consumption is specified at 15 mA maximum, while peak current reaches 50 mA maximum. The output supports an 80 mA maximum load, with residual voltage limited to 1 V at 80 mA and 0.4 V at 10 mA. A special connector provides electrical connection, and a red indicator supplies visual feedback. The fixed slot geometry keeps both optical elements mechanically aligned within the same compact housing.
When the requirement calls for an Omron slot sensor with a 3.6 mm gap and Light-ON behavior, the relevant model is the EE-SPX401. Operating temperature is stated from -10 to 55°C, while storage covers -25 to 65°C. The case is made from polycarbonate, and the supplied shock specification is 500 m/s². Its Light-ON switching distinguishes this unit from the EE-SPX301, which shares the same nominal slot distance but uses Dark-ON operation. This gives two different switching choices without moving to a wider mechanical gap. For the related Dark-ON 3.6 mm configuration, see EE-SPX301.
