Omron EE-SX673A Photomicrosensor
Omron EE-SX673A Photomicrosensor uses a close-mounting structure with a fixed 5 mm through-beam sensing slot for monitoring machine components moving through a compact sensing point. It operates from 5 to 24 VDC and provides an NPN output with selectable Dark-ON or Light-ON switching. Current consumption is specified at 12 mA with the L terminal open, while the output supports up to 100 mA load current. A 4-pole connector provides the electrical interface, and the optical signal is non-modulated. The red indicator operates under the stated no-incident-light condition. For compact mounting around a fixed sensing gap, the EE-SX673A belongs to the photomicrosensor range used with Omron automation.

The Omron EE-SX673A Photomicrosensor uses a close-mounting through-beam arrangement across a fixed 5 mm sensing slot. The built-in sensing sections maintain the optical path inside the sensor body, allowing machine components entering the opening to change the output state without separate sensing heads. It operates from 5 to 24 VDC and provides an NPN output with selectable Dark-ON or Light-ON switching. Current consumption is specified at 12 mA with the L terminal open, while the output supports up to 100 mA load current. Residual voltage is stated at 0.8 V max. with a 100 mA load and 0.4 V max. at 40 mA. A 4-pole connector provides electrical connection, and the optical signal is non-modulated.
Built for close-mounting layouts, the EE-SX673A uses a PBT case with polycarbonate emitter and receiver covers. Its operating temperature range is -25°C to 55°C, while storage extends from -30°C to 80°C without freezing or condensation. The stated vibration specification covers 20 to 2,000 Hz with peak acceleration of 100 m/s² and the specified 1.5 mm double-amplitude test sequence. Shock resistance is 500 m/s² three times along each X, Y, and Z direction, and the enclosure carries an IP50 rating. The NPN output, 100 mA load capacity, selectable switching logic, and compact 5 mm slot distinguish this connector-based configuration.
