Omron EE-SX474 Photomicrosensor
Omron EE-SX474 is a close-mounting through-beam photomicrosensor using a fixed 5 mm slot for target sensing in compact mechanisms. An infrared LED provides the optical source between the integrated transmitting and receiving sections, keeping the sensing path fixed across the opening. 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 supports the output circuit during operation. Its close-mounting format is intended for sensing points positioned near surrounding machine components without requiring separate optical alignment. The EE-SX474 supports the compact through-beam sensor range across Omron Sensing Products.

The Omron EE-SX474 Photomicrosensor uses a close-mounting structure with a built-in through-beam optical path across a fixed 5 mm slot. An infrared LED supplies the sensing light, while the integrated emitter and receiver maintain alignment across the opening inside the sensor body. The model operates from 5 to 24 VDC and provides an NPN output with Light-ON operation. Current consumption is specified at 12 mA max. A 4-pole connector provides the electrical interface, while load short-circuit protection supports the output circuit. Fluorescent-light resistance is specified up to 1,000 lx at the receiver surface under the stated test condition. The fixed internal optical arrangement removes the need to align separate sensing heads and supports mounting near surrounding components in compact mechanisms.
The EE-SX474 operates from -25°C to 55°C and has a storage range from -30°C to 80°C without icing or condensation. PBT is specified as the housing material. The stated vibration specification covers 20 to 2,000 Hz with peak acceleration of 100 m/s² and 1.5 mm double amplitude during the defined test period. Shock resistance is specified at 500 m/s² three times in each X, Y, and Z direction, and the enclosure carries an IP50 rating. Its close-mounting format, fixed 5 mm slot, NPN output, Light-ON operation, and 4-pole connection support compact machine sensing requirements. For another close-mounting model in the same EE Series, refer to the Omron EE-SX473.
