Omron E3Z-LS66-UL Photoelectric Sensor
Omron E3Z-LS66-UL is a distance-settable photoelectric sensor specified with an FGS incident-threshold setting from 40 min. to 200 min. Its 670 nm red LED provides the optical source, while the NPN output communicates the switching state to compatible industrial control circuitry. Selectable Light-ON and Dark-ON operation supports different control requirements. The sensor operates from 12 to 24 VDC and uses an M8 4-pin connector for electrical integration. Current consumption is specified at 30 mA maximum, while response time is 1 ms maximum. A 5-turn endless adjuster supports setting control. Within the E3Z Series, the E3Z-LS66-UL provides adjustable sensing within the distance-settable photoelectric sensor range across Omron Industrial Sensor Products.

The Omron E3Z-LS66-UL Photoelectric Sensor is a distance-settable NPN model with an FGS incident-threshold setting specified from 40 min. to 200 min. A 670 nm red LED provides the optical source, while the output communicates the switching state to compatible industrial control circuitry. The sensor operates from 12 to 24 VDC and consumes up to 30 mA. Load supply voltage is specified up to 26.4 VDC, with load current up to 100 mA and residual voltage of 1 V maximum. Light-ON or Dark-ON operation can be selected, while operate or reset time is specified at 1 ms maximum. A 5-turn endless adjuster provides setting control, and an M8 4-pin connector provides the electrical interface.
For an Omron distance-settable photoelectric sensor requiring NPN output and connector wiring, the relevant model is the E3Z-LS66-UL. Operating temperature is specified from -25 to 55°C, while storage extends from -40 to 70°C. The unit also includes reversed power-supply polarity protection, output short-circuit protection, and mutual-interference prevention. Ambient-light resistance reaches 3,000 lx for incandescent illumination and 10,000 lx for sunlight. Because the supplied data describes an FGS incident-threshold setting rather than a conventional sensing-distance range, no additional distance value should be inferred. For a related NPN connector model with a conventional 20 to 200 mm range, see E3Z-LS66.
