Omron EE-SX473 Photomicrosensor
Omron EE-SX473 is a close-mounting through-beam photomicrosensor built around a fixed 5 mm sensing slot for compact machine installations. An infrared LED provides the internal optical source, while the integrated transmitting and receiving sections maintain the sensing path 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, and a 4-pole connector provides removable electrical integration. Load short-circuit protection is included for the output circuit. Its close-mounting structure is suited to layouts where the sensing point is positioned near surrounding components. The EE-SX473 provides compact mounting within the close-mounting slot sensor range from Omron Compact Sensor Products.

The Omron EE-SX473 Photomicrosensor uses a close-mounting body with a built-in through-beam optical arrangement across a fixed 5 mm slot. The emitter and receiver are integrated into opposite sides of the sensor body, maintaining the sensing path internally rather than using separate optical heads. An infrared LED provides the sensing light, while the NPN output operates in Light-ON mode. The sensor accepts a 5 to 24 VDC supply and consumes up to 12 mA. Electrical connection is provided by a 4-pole connector, 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 condition. The close-mounting format supports compact mechanisms where the sensor must be positioned near surrounding machine components.
The EE-SX473 has an operating temperature range of -25°C to 55°C and a storage range of -30°C to 80°C without icing or condensation. PBT is specified as the housing material. Mechanical specifications include vibration from 20 to 2,000 Hz with peak acceleration of 100 m/s² and 1.5 mm double amplitude under the stated test cycle. Shock resistance is 500 m/s² three times along each X, Y, and Z direction, while the enclosure carries an IP50 rating. Its 5 mm slot, close-mounting structure, NPN output, Light-ON operation, and connector wiring suit compact position and movement sensing requirements.
