Omron EE-SX770 2M Photomicrosensor
Omron EE-SX770 2M is a standard through-beam slot photomicrosensor designed around a fixed 5 mm sensing gap. A GaAs infrared LED operating at 940 nm creates the optical path across the slot and supports sensing of opaque targets as small as 2 × 0.8 mm. The NPN output uses Dark-ON operation, while power is supplied from 5 to 24 VDC. Current consumption is specified at 12 mA maximum. A 2 m pre-wired cable provides the electrical connection, and a red light indicator supplies visual status during operation. The PBT case supports the compact sensor body. Within the EE Series, the EE-SX770 2M fits the infrared slot sensor range from Omron sensing products.

The Omron EE-SX770 2M Photomicrosensor uses a standard through-beam arrangement across a fixed 5 mm slot. A GaAs infrared LED operating at 940 nm creates the optical path across the opening and supports sensing of 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 2 m pre-wired cable provides the electrical connection between the sensor and associated control equipment. A red light indicator supplies visual operating status. The fixed slot geometry provides a consistent sensing point where a target can pass directly through the infrared optical path.
The EE-SX770 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 ratings include vibration from 10 to 2,000 Hz under the stated procedure and shock resistance of 500 m/s² in each axis. The enclosure is rated IP64. Its NPN output, Dark-ON operation, 940 nm infrared source, 5 mm slot, and 2 m cable suit compact applications requiring a defined target passage point. For another NPN 2 m cable model with the same basic 5 mm optical arrangement and a different indicator condition, see the Omron EE-SX770A 2M.
