Omron EE-SX772R 2M Photomicrosensor
Omron EE-SX772R 2M is a T-shaped through-beam slot photomicrosensor designed around a fixed 5 mm sensing gap with PNP switching. Its 940 nm GaAs infrared LED creates the optical path across the opening and supports sensing of opaque targets as small as 2 × 0.8 mm. The sensor operates in Dark-ON mode from a 5 to 24 VDC supply and consumes 12 mA maximum. A 2 m pre-wired cable provides the electrical connection, while the red indicator is specified for the no-incident-light condition. Output short-circuit protection supports the output circuit. For pre-wired T-shaped sensing with PNP output, the EE-SX772R 2M sits within the pre-wired slot sensor range across Omron Sensing Products.

The Omron EE-SX772R 2M Photomicrosensor provides T-shaped through-beam sensing across a fixed 5 mm slot with a PNP output. Its GaAs infrared LED operates at 940 nm and creates the optical path across the opening, supporting opaque targets as small as 2 × 0.8 mm. Dark-ON operation defines the switching response, while the sensor runs from 5 to 24 VDC and consumes 12 mA maximum. A 2 m pre-wired cable provides the electrical connection, and output short-circuit protection supports the output circuit. The red indicator is specified for the no-incident-light condition. This configuration provides a defined slot-sensing point together with a T-shaped body for compact mounting around moving machine components.
The EE-SX772R uses a PBT case and is specified for operation between -25°C and 55°C. Storage temperature extends from -30°C to 80°C, while operating humidity ranges from 5% to 85% without condensation. Mechanical specifications include vibration from 10 to 2,000 Hz under the stated test conditions and shock resistance of 500 m/s² three times along each axis. The enclosure carries an IP64 rating. The PNP output, Dark-ON switching, 940 nm infrared source, and 2 m cable closely align with the EE-SX772P, while the supplied indicator description distinguishes the models. For the related PNP T-shaped model with a standard red light indicator description, refer to the Omron EE-SX772P 2M.
