Omron EE-SX673P Photomicrosensor
Omron EE-SX673P is a close-mounting through-beam slot photomicrosensor designed around a fixed 5 mm sensing gap. Its transmitting and receiving elements establish a non-modulated optical path across the opening, allowing the PNP output condition to change when a target passes through the slot. Light-ON and Dark-ON operation can be selected to suit the required switching logic, while operating power is supplied from 5 to 24 VDC. Current consumption is specified at 12 mA with the L terminal open, and the output supports a 50 mA maximum load. A 4-pole connector provides the electrical interface. The EE-SX673P supports the close-mounting slot sensor range across Omron sensing solutions.

The Omron EE-SX673P Photomicrosensor uses a close-mounting through-beam arrangement with a fixed 5 mm slot. The transmitting and receiving elements are positioned on opposite sides of the opening, creating a defined optical path that changes when a target passes through the sensing area. This model provides a PNP output and supports selectable Dark-ON and Light-ON operation, allowing the switching condition to match the connected control circuit. Operating voltage is 5 to 24 VDC, while current consumption is specified at 12 mA with the L terminal open. The output supports a maximum load current of 50 mA and has a stated residual voltage of 1.3 V maximum at that load. A 4-pole connector provides the electrical connection, while the optical operation is non-modulated and a red light indicator gives visual status.
The EE-SX673P uses a PBT case with polycarbonate emitter and receiver covers. Its operating temperature range is -25°C to 55°C, while storage temperature extends from -30°C to 80°C. Vibration resistance is specified from 20 to 2,000 Hz with peak acceleration of 100 m/s², and shock resistance is rated at 500 m/s² three times in each X, Y, and Z direction. The enclosure carries an IP50 rating. This PNP configuration suits compact machine mechanisms requiring a fixed 5 mm slot with connector-based wiring. For another PNP close-mounting model using the same 5 mm sensing gap but a different indicator arrangement, see the Omron EE-SX673R.
