Omron EE-SX772 2M Photomicrosensor
Omron EE-SX772 2M is a T-shaped through-beam slot photomicrosensor designed around a fixed 5 mm sensing gap. A 940 nm GaAs infrared LED establishes the optical path across the slot and supports sensing of 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, and a red light indicator provides visual operating status. A 2 m pre-wired cable provides the electrical connection, while output short-circuit protection supports the output circuit. Within the EE Series, the EE-SX772 2M supports the T-shaped slot sensor range from Omron Sensor Products.

The Omron EE-SX772 2M Photomicrosensor uses a T-shaped body with a built-in through-beam optical path across a fixed 5 mm slot. A GaAs infrared LED operating at 940 nm provides the sensing light, and the optical arrangement supports opaque targets as small as 2 × 0.8 mm. The sensor provides an NPN output with Dark-ON operation and runs from a 5 to 24 VDC supply. Current consumption is specified at 12 mA maximum. A red light indicator provides operating status, while the 2 m pre-wired cable supports direct electrical connection from the sensing point. Output short-circuit protection is included in the circuit. The defined slot position and T-shaped body support compact installations where a target moves directly through the sensing opening.
The EE-SX772 uses a PBT case and operates from -25°C to 55°C, while storage temperature extends from -30°C to 80°C. Operating humidity is specified from 5% to 85% without condensation. Mechanical resistance includes vibration from 10 to 2,000 Hz under the stated test conditions and shock resistance of 500 m/s² in each X, Y, and Z direction. The enclosure is rated IP64. Its NPN output, Dark-ON switching, 940 nm infrared source, and 2 m cable make this model suitable for T-shaped slot sensing where the target passes through a consistent 5 mm opening. For a related T-shaped NPN model with the red indicator specified for the no-incident-light condition, see the Omron EE-SX772A 2M.
