Omron EE-SX673-WR 1M Photomicrosensor
Omron EE-SX673-WR 1M is a close-mounting through-beam photomicrosensor using a fixed 5 mm sensing slot and a 1 m pre-wired cable. An infrared LED provides the optical source between the integrated transmitting and receiving sections, while the NPN output responds as a target moves through the sensing gap. Dark-ON and Light-ON operation can be selected according to the required switching logic. The sensor operates from 5 to 24 VDC and consumes 12 mA maximum. Load short-circuit protection is included, while fluorescent-light resistance is specified up to 1,000 lx at the receiver surface. Its compact body supports sensing near surrounding machine components. The EE-SX673-WR 1M provides pre-wired integration within the close-mounting slot sensor range from Omron Pre-Wired Sensor Products.

The Omron EE-SX673-WR 1M Photomicrosensor uses a close-mounting structure with a built-in through-beam optical path across a fixed 5 mm slot. An infrared LED provides the sensing light, while the integrated optical sections maintain the beam across the opening. The sensor operates from 5 to 24 VDC and provides an NPN output with selectable Dark-ON or Light-ON operation. Current consumption is specified at 12 mA max., and a 1 m pre-wired cable provides the electrical connection. Load short-circuit protection is included. Fluorescent-light resistance is stated up to 1,000 lx at the receiver surface under the specified condition. The close-mounting profile supports compact mechanisms where the sensing point must sit near surrounding machine structures.
With PBT specified as the housing material, the EE-SX673-WR operates from -25°C to 55°C and can be stored from -30°C to 80°C without icing or condensation. The stated vibration range extends from 20 to 2,000 Hz with peak acceleration of 100 m/s² and the specified 1.5 mm double-amplitude test cycle. Shock resistance is 500 m/s² three times in each X, Y, and Z direction, while the enclosure carries an IP50 rating. Its 5 mm slot, NPN output, selectable switching logic, close-mounting profile, and 1 m cable provide a direct-wired option for compact machine installations.
