Omron EE-SX671R Photomicrosensor
Omron EE-SX671R is an L-shaped through-beam photomicrosensor designed around a fixed 5 mm sensing slot with PNP switching. Its integrated transmitting and receiving sections establish a non-modulated optical path across the opening, allowing the output state to respond when a target passes through the slot. Dark-ON and Light-ON operation can be selected according to the required control logic. Operating power is supplied from 5 to 24 VDC, while current consumption is specified at 12 mA with the L terminal open. The output supports up to 50 mA load current, and a 4-pole connector provides the electrical interface. The EE-SX671R provides a defined L-shaped mounting orientation within the PNP slot sensor range from Omron Sensor Products.

The Omron EE-SX671R Photomicrosensor uses an L-shaped through-beam arrangement across a fixed 5 mm sensing slot. Its built-in sensing sections maintain an optical path across the opening, allowing a machine component moving through the slot to change the output state. The unit operates from 5 to 24 VDC and provides a PNP output with selectable Dark-ON or Light-ON switching. Current consumption is specified at 12 mA with the L terminal open, while the output supports a maximum load current of 50 mA. Residual voltage is specified at 1.3 V max. at a 50 mA load. A 4-pole connector provides the electrical interface, while the non-modulated optical signal supports the stated slot-sensing arrangement.
Built around an L-shaped mounting format, the EE-SX671R uses a PBT case with polycarbonate emitter and receiver covers. Its operating temperature range extends from -25°C to 55°C, while storage covers -30°C to 80°C without freezing or condensation. Mechanical resistance includes vibration from 20 to 2,000 Hz with peak acceleration of 100 m/s² and the specified 1.5 mm double-amplitude test sequence. Shock resistance is stated at 500 m/s² three times in each X, Y, and Z direction, while the enclosure carries an IP50 rating. The PNP output and selectable switching logic suit compact machine arrangements requiring an L-shaped 5 mm slot. For a related L-shaped NPN model, see the Omron EE-SX671.
