Omron E3Z-LS66 Photoelectric Sensor
Omron E3Z-LS66 is a distance-settable photoelectric sensor using background suppression across a specified 20 to 200 mm range. Its 670 nm red LED provides the optical source, while the PNP output communicates the switching state to compatible machine-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. Operation and stability indicators provide visual information during setup. Within the E3Z Series, the E3Z-LS66 provides connector-based sensing within the 200 mm background suppression sensor range across Omron Sensing Products.

The Omron E3Z-LS66 Photoelectric Sensor uses distance-settable background-suppression sensing across a specified 20 to 200 mm range. A 670 nm red LED provides the optical source, while the NPN 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, and operate or reset time is specified at 1 ms maximum. An M8 4-pin connector provides the electrical interface, while orange operation and green stability indicators support visual setup checks.
For an Omron background suppression photoelectric sensor requiring NPN output and connector wiring, the relevant model is the E3Z-LS66. Operating temperature is specified from -25 to 55°C, with storage from -40 to 70°C under the stated conditions. Ambient-light resistance reaches 3,000 lx for incandescent illumination and 10,000 lx for sunlight. Reversed power-supply polarity protection, output short-circuit protection, and mutual-interference prevention are included. Its characteristics suit requirements for an Omron 200 mm BGS sensor, Omron NPN M8 photoelectric sensor, and connector-based distance sensor. For a related NPN connector model using a shorter 2 to 80 mm BGS range, see E3Z-LS68.
