Omron EE-SX952-W 1M — amplified through-beam slot sensor
The Omron EE-SX952-W 1M is an amplified through-beam photoelectric sensor from the EE-SX95 series, designed for tight-space object detection in industrial automation. It operates on a 24 VDC supply and provides an NPN output that is selectable between Dark-ON and Light-ON logic, giving the integrator flexibility to match PLC input polarity without external inversion. The slot gap is 0.197 mm, sized for edge detection of thin webs, labels, or small parts on a conveyor or indexing station. The sensor is chassis-mounted and rated for -25°C to 55°C ambient, covering most indoor factory-floor environments.
0.197 mm slot — what it means for the pick
The slot gap is 0.197 mm. The EE-SPX613 peer has a 0.236 mm slot.
NPN output — Dark-ON / Light-ON selectable
The output is NPN open-collector, rated to sink 0.05 A. The Dark-ON / Light-ON selection is done via wiring or a switch (check the specific model's connection diagram), so no extra logic gate is needed to invert the sense. This is a common requirement when retrofitting a sensor into a legacy PLC input card that expects a sinking signal. The 0.05 A switching current is sufficient for direct PLC inputs or small relays; for higher loads, buffer with an interposing relay.
Mounting and wiring
Chassis-mount package with wire leads — no connector, so plan for a junction box or terminal block within the cable run. The sensor is amplified, meaning the electronics are built-in; no separate amplifier module is required. The 1 m cable length (suffix "1M") is standard; if the application needs longer reach, extend via a shielded cable, keeping the total loop within the 24 VDC supply's current budget. The -25°C to 55°C operating range covers unheated warehouses and production floors; avoid direct steam or washdown areas.
