Omron EE-SX951-W 3M Photomicrosensor
Omron EE-SX951-W 3M is an L-shaped through-beam slot photomicrosensor designed around a fixed 5 mm sensing gap with a standard 3 m pre-wired cable. Its NPN output supports both Light-ON and Dark-ON modes, allowing the switching response to match different control requirements. The sensor operates from 5 to 24 VDC and consumes 15 mA, while the output supports a maximum load current of 50 mA. A red light indicator provides visual operating status, and the non-modulated optical arrangement establishes a defined sensing position across the slot. Compared with the 1 m version, this model provides additional cable length. The EE-SX951-W 3M belongs to the pre-wired slot sensor range across Omron industrial sensing.

The Omron EE-SX951-W 3M Photomicrosensor uses an L-shaped body with a fixed 5 mm through-beam sensing slot. Its NPN output supports both Light-ON and Dark-ON modes, allowing the switching logic to suit the connected control circuit. The sensor operates from 5 to 24 VDC and consumes 15 mA. Maximum load current is specified at 50 mA, while residual voltage is 0.7 V maximum at a 50 mA load and 0.4 V maximum at 5 mA. A red light indicator provides operating status, and the optical arrangement is non-modulated. A standard 3 m pre-wired cable provides additional routing distance from the sensing position to the control section compared with the shorter 1 m version.
The EE-SX951-W uses PBT for the case and cover, with polycarbonate specified for the emitter and receiver sections. Operating temperature ranges from -25°C to 55°C, while storage extends from -30°C to 80°C. Mechanical resistance includes vibration from 10 to 2,000 Hz under the stated test procedure and shock resistance of 500 m/s² in each X, Y, and Z direction. The enclosure carries an IP50 rating. Its L-shaped geometry, NPN output, selectable switching modes, and longer standard cable suit fixed installations that require greater cable reach without using a robot cable. For a related version using the same L-shaped 5 mm slot with a shorter standard cable, see the Omron EE-SX951-W 1M.
