Omron EE-SX975-C1 Photomicrosensor
Omron EE-SX975-C1 is a T-shaped through-beam slot photomicrosensor designed with a fixed 5 mm sensing gap and a slot center positioned at 10 mm. Its NPN output supports both Light-ON and Dark-ON operation, allowing the switching logic to suit 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. An orange light indicator provides visual operating status, and a 4-pole connector provides the electrical interface. The non-modulated optical arrangement establishes the sensing point across the slot, while the 10 mm slot-center dimension defines the T-shaped mounting geometry. The EE-SX975-C1 belongs to the T-shaped photomicrosensor range from Omron Automation Sensors.

The Omron EE-SX975-C1 Photomicrosensor uses a T-shaped through-beam sensing arrangement with a fixed 5 mm slot and a slot center positioned at 10 mm. Its NPN output supports both Light-ON and Dark-ON modes, 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, with residual voltage of 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 the electrical interface. The 10 mm slot-center dimension defines the mounting position of the sensing opening within the T-shaped body.
The EE-SX975-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 test conditions and shock resistance of 500 m/s² in each axis. The enclosure carries an IP50 rating. Compared with the EE-SX972-C1, this model retains NPN switching, a 5 mm slot, selectable Light-ON or Dark-ON operation, and a 4-pole connector but positions the slot center at 10 mm rather than 7 mm. For the 7 mm slot-center alternative, refer to the Omron EE-SX972-C1.
