Omron EE-SX974-C1 Photomicrosensor
Omron EE-SX974-C1 is a close-mounting through-beam slot photomicrosensor designed around a fixed 5 mm sensing gap. Its NPN output supports both Light-ON and Dark-ON operation, allowing the switching response to be selected according to the connected control circuit. The sensor operates from 5 to 24 VDC and consumes 21 mA, while the output supports a maximum load current of 50 mA. Residual voltage is specified at 0.4 V maximum at 5 mA and 1.0 V maximum at 50 mA. An orange light indicator provides visual status, and a 4-pole connector supports detachable wiring. Its close-mounting format provides a compact sensing arrangement. Within the EE Series, the EE-SX974-C1 supports the close-mounting slot sensor range from Omron Detection Sensors.

The Omron EE-SX974-C1 Photomicrosensor uses a close-mounting through-beam arrangement across a fixed 5 mm sensing slot. Its NPN output supports both Light-ON and Dark-ON operation, allowing the switching response to suit different control requirements. The sensor operates from 5 to 24 VDC and consumes 21 mA. Maximum load current is specified at 50 mA, while residual voltage is 0.4 V maximum at a 5 mA load and 1.0 V maximum at 50 mA. An orange light indicator provides operating status, and the optical arrangement is non-modulated. A 4-pole connector provides a detachable electrical interface. The close-mounting format supports installations where the sensing assembly needs to occupy a compact position around the 5 mm slot.
The EE-SX974-C1 uses PBT for the case and cover together with polycarbonate emitter and receiver sections. Operating temperature ranges from -25°C to 55°C without freezing or condensation, while storage extends from -30°C to 80°C. Mechanical resistance includes vibration from 10 to 2,000 Hz under the stated conditions and shock resistance of 500 m/s² along each axis. The enclosure is rated IP50. Its NPN output differentiates this model from the PNP EE-SX974P-C1, while both share the same close-mounting form, 5 mm slot, 21 mA consumption, selectable switching modes, and 4-pole connector. For the corresponding PNP configuration, refer to the Omron EE-SX974P-C1.
