Omron E3Z-LS68 Photoelectric Sensor
Omron E3Z-LS68 is a distance-settable photoelectric sensor using background suppression across a specified 2 to 80 mm range. Its 650 nm red LED provides the optical source, while the NPN output communicates the switching state to compatible machine-control circuitry. Selectable Light-ON and Dark-ON operation supports different switching requirements. The sensor operates from 12 to 24 VDC and uses an M8 connector for electrical integration. A one-turn adjuster supports sensing-point setup, while response time is specified at 1 ms maximum. Ambient-light limits are provided for incandescent light and sunlight. Within the E3Z Series, the E3Z-LS68 supports compact connector wiring within the 80 mm BGS sensor range across Omron Sensing Range.

The Omron E3Z-LS68 Photoelectric Sensor uses distance-settable background-suppression sensing across a specified 2 to 80 mm range. A 650 nm red LED supplies 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 supports selectable Light-ON or Dark-ON operation. Operate or reset time is specified at 1 ms maximum, while a one-turn adjuster allows the sensing point to be set for the required target position. An M8 connector provides the electrical interface without a permanently attached cable. Ambient-light resistance is specified up to 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.
For an Omron short-range BGS sensor requiring NPN output and connector wiring, the relevant model is the E3Z-LS68. Operating temperature extends from -25 to 55°C, while storage is specified from -40 to 70°C under the stated conditions. Operating humidity covers 35% to 85%, and PBT is listed as the housing material. The 2 to 80 mm setting supports close-position sensing where surfaces beyond the selected target point should have reduced influence on switching. Its specification also suits requirements for an Omron 80 mm photoelectric sensor and Omron NPN distance-settable sensor. For a related connector model with a wider 20 to 200 mm range, see E3Z-LS66.
