Omron EE-SX674A Photomicrosensor
Omron EE-SX674A is a close-mounting through-beam slot photomicrosensor with a fixed 5 mm sensing gap and NPN output. Its infrared LED provides the optical source across the slot, while the integrated receiving side monitors changes in that optical path as a target moves through the opening. Light-ON and Dark-ON operation can be selected to suit different control requirements. The unit operates from 5 to 24 VDC and has a maximum current consumption of 12 mA. Electrical integration is handled through a 4-pole connector, while the indicator shows the no-incident-light condition. Load short-circuit protection is also specified for the output circuit. The EE-SX674A supports the compact slot sensor range across Omron Automation Sensors.

The Omron EE-SX674A Photomicrosensor uses a close-mounting through-beam arrangement with a fixed 5 mm sensing slot. An infrared LED provides the optical source across the opening, and the integrated receiving side responds as an object passes through that defined sensing position. The unit provides an NPN output and allows Dark-ON or Light-ON operation to be selected according to the required control logic. Supply voltage is specified from 5 to 24 VDC, while maximum current consumption is 12 mA. A 4-pole connector provides the electrical interface, and the indicator shows the no-incident-light state. Load short-circuit protection is included in the stated specifications. Ambient illumination is rated up to 1,000 lx when fluorescent light reaches the surface of the receiver, supporting operation under the stated surrounding-light condition.
The EE-SX674A uses a PBT housing and operates from -25°C to 55°C, while its storage range extends from -30°C to 80°C. Vibration resistance is specified across 20 to 2,000 Hz with peak acceleration of 100 m/s², and shock resistance is 500 m/s² three times in each X, Y, and Z direction. The enclosure carries an IP50 rating. Its 5 mm slot, NPN output, selectable switching logic, and 4-pole connector provide a compact arrangement for machine mechanisms where the sensing point must remain physically defined by the slot. For another NPN connector model from the same close-mounting group, see the Omron EE-SX674.
