Omron EE-SX472 Photomicrosensor
Omron EE-SX472 is a T-shaped through-beam photomicrosensor designed with a fixed 5 mm sensing slot and a slot center positioned at 7 mm. An infrared LED provides the optical source between the integrated transmitting and receiving sections, allowing the NPN output to respond when a target passes through the opening. Light-ON operation defines the switching condition, while operating power is supplied from 5 to 24 VDC. Current consumption is specified at 12 mA maximum, and a 4-pole connector provides the electrical interface. Load short-circuit protection supports the output circuit. Its T-shaped structure establishes a defined mounting geometry around the sensing gap. The EE-SX472 supports the T-shaped photomicrosensor range across Omron Automation Sensor Products.

The Omron EE-SX472 Photomicrosensor uses a T-shaped body with a fixed 5 mm through-beam sensing slot and a slot center positioned at 7 mm. An infrared LED provides the optical source, while the integrated emitter and receiver establish the sensing path across the opening. When a machine component passes through the slot, it changes this optical path and produces the specified NPN output response. The sensor operates from 5 to 24 VDC in Light-ON mode and consumes up to 12 mA. A 4-pole connector provides electrical connection, while load short-circuit protection supports the output circuit. Fluorescent-light resistance is specified up to 1,000 lx on the receiver surface under the stated condition. Its T-shaped structure and defined 7 mm slot-center position distinguish it from other 5 mm EE-SX body formats.
The EE-SX472 operates from -25°C to 55°C and can be stored 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 sequence. Shock resistance is 500 m/s² three times in each X, Y, and Z direction. The enclosure carries an IP50 rating. Its T-shaped mounting geometry, 5 mm slot, NPN switching, 4-pole connector, and Light-ON operation suit compact mechanical arrangements where slot position is important. For a related close-mounting EE Series slot model with the same 5 mm sensing gap, see the Omron EE-SX473.
