Omron EE-SX677-WR 1M Photomicrosensor
Omron EE-SX677-WR 1M is an R-shaped through-beam slot photomicrosensor with a fixed 5 mm sensing gap and a 1 m pre-wired cable. Its infrared LED establishes the optical path across the slot, while the NPN output provides the switching signal as a target enters or leaves the sensing opening. Light-ON or Dark-ON operation can be selected to match the required control sequence. The sensor operates from 5 to 24 VDC and consumes 12 mA maximum. Load short-circuit protection supports the output circuit, while the pre-wired connection suits compact machine layouts. The EE-SX677-WR 1M provides pre-wired R-shaped sensing within the slot sensing sensor range across Omron machine automation.

The Omron EE-SX677-WR 1M Photomicrosensor uses an R-shaped body with a fixed 5 mm through-beam slot and an integrated 1 m pre-wired cable. An infrared LED forms the internal optical path between the emitter and receiver, and the NPN output changes according to the target condition as an object enters or leaves the slot. Light-ON or Dark-ON operation can be selected to suit the required switching logic. The sensor operates from 5 to 24 VDC and consumes 12 mA maximum. Load short-circuit protection supports the output circuit. Ambient fluorescent-light resistance is specified up to 1,000 lx at the receiver surface under the stated conditions, while the pre-wired arrangement supports direct connection from the sensing location.
The EE-SX677-WR uses PBT for the body and is specified for operation from -25°C to 55°C, with storage from -30°C to 80°C. Vibration resistance extends from 20 to 2,000 Hz under the listed test conditions, and shock resistance is specified at 500 m/s² in the X, Y, and Z directions. The enclosure carries an IP50 rating. Its R-shaped format and 1 m cable make it suitable where the sensor must be placed in a compact mechanical position with direct wiring routed back to the control section. For the connector-type R-shaped version with the same 5 mm slot and NPN output, refer to the Omron EE-SX677.
