Omron EE-SX471 Photomicrosensor
Omron EE-SX471 is an L-shaped through-beam photomicrosensor designed around a fixed 5 mm sensing slot. An infrared LED provides the optical source between the integrated transmitting and receiving sections, while the L-shaped structure offers a distinct mounting arrangement around the sensing point. The sensor operates from 5 to 24 VDC and provides an NPN output with Light-ON operation. Current consumption is specified at 12 mA maximum, while a 4-pole connector provides the electrical interface. Load short-circuit protection is included for the output circuit. The built-in optical arrangement keeps the sensing path fixed across the slot without separate optical alignment. The EE-SX471 provides an L-shaped format within the 5 mm slot sensor range from Omron Industrial Sensors.

The Omron EE-SX471 Photomicrosensor uses an L-shaped body with a built-in through-beam optical path across a fixed 5 mm slot. The internal emitter and receiver maintain the sensing path within the sensor itself, so separate optical components do not need to be aligned across the machine. An infrared LED supplies the sensing light, while the NPN output operates in Light-ON mode. The model runs from 5 to 24 VDC and consumes up to 12 mA. A 4-pole connector provides electrical connection, and load short-circuit protection is included. Fluorescent-light resistance is specified at up to 1,000 lx on the receiver surface under the stated test condition. The L-shaped format differentiates this model from the standard EE-SX470 while retaining the same specified slot width and basic electrical arrangement.
The EE-SX471 is specified for operation from -25°C to 55°C and storage from -30°C to 80°C without icing or condensation. PBT is listed as the housing material. Mechanical resistance includes the stated vibration range from 20 to 2,000 Hz, with peak acceleration of 100 m/s² and 1.5 mm double amplitude during the specified test cycle. Shock resistance is 500 m/s² three times in each X, Y, and Z direction. The enclosure is rated IP50. Its L-shaped body supports installations where mounting geometry differs from a straight standard slot sensor while retaining the 5 mm sensing gap, NPN output, connector wiring, and Light-ON operation. For the standard body alternative, refer to the Omron EE-SX470.
