Omron EE-SPX301 Photomicrosensor
Omron EE-SPX301 is a slot-type photomicrosensor built around a fixed 3.6 mm through-beam sensing gap. An object entering the slot interrupts the modulated optical path and changes the NPN output condition. Dark-ON operation defines the switching response, while a special connector provides electrical integration with compatible machine-control circuitry. The sensor operates from 5 to 24 VDC, with average current consumption specified at 15 mA maximum and peak consumption at 50 mA maximum. Output load current is rated up to 80 mA, and a red indicator provides visual status information. The compact slot geometry establishes a repeatable sensing position. The EE-SPX301 provides compact optical switching within the 3.6 mm slot sensor range across Omron Miniature Slot Sensors.

The Omron EE-SPX301 Photomicrosensor establishes a through-beam optical path across a fixed 3.6 mm slot. When a target enters this narrow gap, the modulated beam changes and the NPN output follows the Dark-ON switching condition. The unit operates from 5 to 24 VDC, with average current consumption specified at 15 mA maximum and a peak value of 50 mA. Maximum load current is 80 mA. Residual voltage is limited to 1 V at an 80 mA load and 0.4 V at 10 mA. A special connector provides the electrical interface, while a red indicator gives visual switching feedback. Its compact geometry keeps the optical relationship fixed, avoiding the need to align separate external sensing units.
For an Omron slot photomicrosensor requiring Dark-ON operation and a 3.6 mm fixed gap, the relevant model is the EE-SPX301. Operating temperature covers -10 to 55°C, while storage extends from -25 to 65°C. The housing is specified in polycarbonate, and shock resistance is stated at 500 m/s². Its 80 mA maximum load capability distinguishes the electrical arrangement from some later SPX models with lower load limits. The 3.6 mm sensing opening is also useful when the target path must remain mechanically constrained within a narrow gap. For a related model using the same 3.6 mm slot but Light-ON switching, see EE-SPX401.
