Omron EE-SX772A 2M Photomicrosensor
Omron EE-SX772A 2M is a T-shaped through-beam slot photomicrosensor with a fixed 5 mm sensing gap for compact object sensing. Its GaAs infrared LED operates at 940 nm and supports opaque targets as small as 2 × 0.8 mm. The sensor provides an NPN output with Dark-ON switching and operates from a 5 to 24 VDC supply. Current consumption is specified at 12 mA maximum. A 2 m pre-wired cable provides the electrical interface, while the red indicator is specified for the no-incident-light condition. Output short-circuit protection is also provided. For compact T-shaped sensing with a defined slot position, the EE-SX772A 2M belongs to the through-beam slot sensor range across Omron Industrial Sensors.

The Omron EE-SX772A 2M Photomicrosensor uses a T-shaped through-beam arrangement with a fixed 5 mm sensing slot. A 940 nm GaAs infrared LED establishes the optical path across the opening and supports opaque targets as small as 2 × 0.8 mm. The NPN output operates in Dark-ON mode, while power is supplied from 5 to 24 VDC. Current consumption is specified at 12 mA maximum. This model uses a 2 m pre-wired cable for electrical connection and includes output short-circuit protection. The red indicator is specified for the no-incident-light condition, providing a clear distinction from the indicator description listed for some related models. The fixed slot and T-shaped body provide a defined sensing point for moving tabs, plates, or similar mechanical elements.
The EE-SX772A uses a PBT case and is specified for operation from -25°C to 55°C. Storage temperature extends from -30°C to 80°C, while operating humidity ranges from 5% to 85% without condensation. Its mechanical specifications include vibration from 10 to 2,000 Hz with the stated peak acceleration and shock resistance of 500 m/s² three times in each axis. The enclosure carries an IP64 rating. Electrically, it retains the NPN output, Dark-ON mode, 5 to 24 VDC supply, and 2 m cable used in the related EE-SX772. The key indicator description in the supplied data is no incident light in red. For the related T-shaped NPN version with a standard red light indicator description, refer to the Omron EE-SX772 2M.
