Omron EE-SX677 Photomicrosensor
Omron EE-SX677 is an R-shaped through-beam slot photomicrosensor designed around a fixed 5 mm sensing gap for compact position and movement sensing. An infrared LED forms the internal optical path between the integrated emitter and receiver, while the NPN output changes according to the target condition inside the slot. Light-ON or Dark-ON operation can be selected to suit the required machine logic. The sensor operates from 5 to 24 VDC and consumes 12 mA maximum. A 4-pole connector provides the electrical interface, and load short-circuit protection supports the output circuit. For R-shaped slot applications, the EE-SX677 sits within the industrial photomicrosensor range available from Omron sensing products.

The Omron EE-SX677 Photomicrosensor uses an R-shaped housing with a built-in through-beam optical path across a fixed 5 mm slot. An infrared LED provides the internal sensing light, and the NPN output changes according to the target condition as a component passes through the opening. Light-ON or Dark-ON operation can be selected to match the required control logic. The sensor operates from 5 to 24 VDC and consumes 12 mA maximum. A 4-pole connector provides the electrical interface, while load short-circuit protection supports the output circuit. Fluorescent-light resistance is specified up to 1,000 lx at the receiver surface under the listed conditions, supporting stable operation within the stated ambient-light limit.
The EE-SX677 uses a PBT body and operates from -25°C to 55°C, with storage specified from -30°C to 80°C. Its mechanical ratings include vibration from 20 to 2,000 Hz and shock resistance of 500 m/s² under the stated test procedures. The enclosure carries an IP50 rating. The R-shaped geometry provides a different mounting form from the F-shaped EE-SX676 while retaining the same 5 mm slot, NPN output, selectable Light-ON or Dark-ON mode, and 4-pole connector. For a related R-shaped version that replaces the connector with a 1 m pre-wired cable, see the Omron EE-SX677-WR 1M.
