Omron EE-SX673R Photomicrosensor
Omron EE-SX673R is a close-mounting through-beam slot photomicrosensor with a fixed 5 mm sensing gap and PNP output. The transmitting and receiving elements establish a non-modulated optical path across the slot, allowing the output state to change when an object moves through the opening. Light-ON and Dark-ON operation can be selected according to the required machine logic, while the sensor operates from 5 to 24 VDC. Current consumption is specified at 12 mA with the L terminal open, and the output supports a 50 mA maximum load. A 4-pole connector provides the electrical interface, while a red indicator shows the no-incident-light state. The EE-SX673R belongs to the 5 mm slot photomicrosensor range across Omron Sensors.

The Omron EE-SX673R Photomicrosensor provides close-mounting through-beam sensing across a fixed 5 mm slot. Its transmitting and receiving elements maintain the optical path across the opening, and the PNP output changes according to the selected operating logic as a target enters the sensing area. Both Dark-ON and Light-ON operation are available, giving flexibility when matching the sensor state with the connected control circuit. The unit operates from 5 to 24 VDC and consumes 12 mA with the L terminal open. Maximum load current is specified at 50 mA, with residual voltage of 1.3 V maximum at that load. Electrical connection is made through a 4-pole connector. The optical operation is non-modulated, while a red indicator shows the no-incident-light condition for visual status during setup and operation.
The EE-SX673R uses a PBT case with polycarbonate covers around the emitter and receiver sections. It operates from -25°C to 55°C and can be stored from -30°C to 80°C. Its vibration specification covers 20 to 2,000 Hz with a peak acceleration of 100 m/s², while shock resistance is 500 m/s² three times in each X, Y, and Z direction. The enclosure is rated IP50. The close-mounting form and 5 mm gap provide a defined sensing position where a compact connector-type PNP unit is required. For another PNP close-mounting model using a 5 mm slot and 4-pole connector, see the Omron EE-SX673P.
