Omron EE-SX977-C1 Photomicrosensor
Omron EE-SX977-C1 is an R-shaped through-beam slot photomicrosensor built around a fixed 5 mm sensing gap with a 4-pole connector. The NPN output supports both Light-ON and Dark-ON operation, allowing the switching response to suit different machine-control requirements. 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 operating status, while the optical arrangement is non-modulated. Its R-shaped body provides a distinct mounting geometry within the connector-type models. The EE-SX977-C1 belongs to the slot-type photomicrosensor range from Omron sensing products.

The Omron EE-SX977-C1 Photomicrosensor uses an R-shaped through-beam arrangement across a fixed 5 mm sensing slot. Its NPN output supports both Light-ON and Dark-ON modes, allowing the switching response to be selected according to the connected control logic. The sensor operates from 5 to 24 VDC and consumes 21 mA. Its output supports a maximum load current of 50 mA, with residual voltage specified at 0.4 V maximum at a 5 mA load and 1.0 V maximum at 50 mA. An orange light indicator provides visual operating status, while the optical arrangement is non-modulated. A 4-pole connector provides the electrical interface, and the R-shaped body establishes a distinct mechanical mounting format around the defined sensing opening.
The EE-SX977-C1 uses PBT for the case and cover, with polycarbonate specified for the 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 test procedure and shock resistance of 500 m/s² along each axis. The enclosure carries an IP50 rating. Its R-shaped form differentiates it from the F-shaped EE-SX976-C1 while retaining the same 5 mm slot, NPN output, selectable switching modes, 21 mA consumption, and 4-pole connector. For the related F-shaped configuration, refer to the Omron EE-SX976-C1.
