It operates on a 12 V supply and delivers an NPN open-collector output that can be wired for either Dark-ON or Light-ON logic via a selector switch — no firmware inversion needed at the PLC input. The chassis-mount package suits fixed-position installation on conveyor guides, pick-and-place grippers, or label applicator frames where the 0.512 mm slot width matches the target's thickness or flag profile. ## Selectable Dark-ON / Light-ON — one sensor, two logic states The NPN output can be configured as Dark-ON (output conducts when the beam is blocked) or Light-ON (output conducts when the beam is uninterrupted). This selector eliminates the need for a separate inverter or software logic reversal at the controller. The 0.512 mm slot is narrow — verify the flag or part thickness clears the gap without rubbing, and that the target material is opaque enough to interrupt the beam reliably. ## Temperature range — indoor controlled environments Rated for -10°C to 55°C ambient. This covers most indoor factory-floor and light-industrial settings, but not freezers, ovens, or outdoor enclosures without climate control. The 0.512 mm slot is sensitive to thermal expansion of the mounting bracket — allow for alignment drift if the sensor is near a heat source.","metaTitle":"Omron EE-SPX303N Through-Beam Sensor, 0.512 mm Slot, NPN Selectable","metaDescription":"Omron EE-SPX303N through-beam optical sensor with 0.512 mm sensing distance, 12 V supply, NPN Dark-ON/Light-ON selectable output.
