Omron EE-SX951-R 3M Photomicrosensor
Omron EE-SX951-R 3M is an L-shaped through-beam slot photomicrosensor with a fixed 5 mm sensing gap and an extended 3 m robot cable. The NPN output supports both Light-ON and Dark-ON operating modes, allowing the required switching response to be selected for compatible control circuitry. Operating power is supplied from 5 to 24 VDC, while current consumption is specified at 15 mA. The output supports a maximum load current of 50 mA, and a red light indicator provides operating status. Its non-modulated optical arrangement retains the same sensing principle as the shorter cable version while providing additional wiring length. The EE-SX951-R 3M supports longer-cable installation within the slot-type optical sensor range from Omron Industrial Sensor Products.

The Omron EE-SX951-R 3M Photomicrosensor uses an L-shaped through-beam optical arrangement across a fixed 5 mm slot and includes an extended 3 m robot cable. Its NPN output supports both Light-ON and Dark-ON operating modes, allowing the switching response to suit different control requirements. 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 visual status, and the optical arrangement is non-modulated. The longer cable provides additional routing distance from the sensing position to the connected control circuitry.
The EE-SX951-R uses PBT for the case and cover together with polycarbonate emitter and receiver sections. Its operating temperature range is -25°C to 55°C, with storage from -30°C to 80°C. Mechanical specifications include vibration from 10 to 2,000 Hz under the stated test procedure and shock resistance of 500 m/s² along each axis. The enclosure carries an IP50 rating. Compared with the 1 m robot-cable version, this model retains the same L-shaped 5 mm slot arrangement, NPN output, selectable switching modes, and electrical characteristics while increasing available cable length to 3 m. For a shorter cable installation using the same stated configuration, see the Omron EE-SX951-R 1M.
