Omron EE-SX670A Photomicrosensor
Omron EE-SX670A is a standard through-beam slot photomicrosensor designed around a fixed 5 mm sensing gap. Its integrated transmitting and receiving sections establish a non-modulated optical path across the opening, allowing the NPN output condition to respond when a target passes through the slot. Dark-ON and Light-ON operation can be selected according to the required switching logic. The sensor operates from 5 to 24 VDC, with current consumption specified at 12 mA while the L terminal is open. The output supports up to 100 mA load current, and a 4-pole connector provides the electrical interface. A red indicator operates under the stated no-incident-light condition. The EE-SX670A supports the standard 5 mm sensor range from Omron Photomicrosensor Products.

The Omron EE-SX670A Photomicrosensor uses a standard through-beam arrangement across a fixed 5 mm sensing slot. Its built-in sensing sections maintain the optical path inside the sensor body, allowing a machine component moving through the slot to change the output state without separately mounted optical heads. The unit operates from 5 to 24 VDC and provides an NPN output with selectable Dark-ON or Light-ON switching. Current consumption is specified at 12 mA with the L terminal open. The output supports up to 100 mA load current, while residual voltage is specified at 0.8 V max. with a 100 mA load and 0.4 V max. with a 40 mA load. A 4-pole connector provides the electrical interface, and the optical signal is non-modulated. The red indicator operates under the stated no-incident-light condition.
The EE-SX670A uses a PBT case with polycarbonate emitter and receiver covers. Operating temperature extends from -25°C to 55°C, while storage temperature covers -30°C to 80°C without freezing or condensation. Mechanical resistance includes the stated 20 to 2,000 Hz vibration range with peak acceleration of 100 m/s² and 1.5 mm double amplitude during the specified test sequence. Shock resistance is 500 m/s² three times along each X, Y, and Z direction, while the enclosure is rated IP50. Its standard body, NPN output, selectable switching logic, and 4-pole connection suit compact slot-sensing arrangements. For a related PNP model using the same standard 5 mm slot format, see the Omron EE-SX670P.
