The Omron EE-SX954P-W 1M is an amplified through-beam photoelectric sensor from the EE-SX95 series, designed for detecting objects passing through a 0.197 mm slot. Its PNP output is selectable between Dark-ON and Light-ON, giving the controls integrator flexibility to match the logic sense of the downstream PLC or counter input without an external inverter. The sensor operates on a 24 V supply, which is the standard industrial bus voltage, so no extra DC-DC converter is needed in the cabinet. Typical applications include edge detection on a conveyor, label registration in packaging machinery, or counting parts on a pick-and-place line — anywhere a small object interrupts a narrow beam and the controller expects a PNP signal.
The 0.197 mm gap is the distance between emitter and receiver in the fork.
PNP output with Dark-ON/Light-ON selection
The PNP output sources current when the beam is blocked or unblocked, depending on wiring selection. Switching current is rated at 0.05 A.
For a functional alternative with an NPN output, the EE-SPX613 is a through-beam amplified sensor with a slightly wider 0.236 mm slot and a -10°C to 55°C range — but the output logic differs, so verify the PLC input type before substituting.
