Omron E3Z-LS88 Photoelectric Sensor
Omron E3Z-LS88 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 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 connector for electrical integration. Current consumption is specified at 30 mA maximum, while response time is 1 ms maximum. A one-turn adjuster supports sensing-point setup for the required target position. Within the E3Z Series, the E3Z-LS88 provides short-range connector wiring within the 80 mm PNP BGS sensor range across Omron Sensing Products.

The Omron E3Z-LS88 Photoelectric Sensor uses distance-settable background-suppression sensing across a specified 2 to 80 mm range. A 650 nm red LED provides the optical source, while the PNP output communicates the switching state to compatible industrial control circuitry. The sensor operates from 12 to 24 VDC and consumes up to 30 mA. Light-ON or Dark-ON operation can be selected according to the required control logic, while operate or reset time is specified at 1 ms maximum. A one-turn adjuster allows the sensing point to be set for the required target position, and an M8 connector provides the electrical interface. Ambient-light resistance reaches 3,000 lx for incandescent illumination and 10,000 lx for sunlight under the stated conditions.
For an Omron short-range background suppression sensor requiring PNP output and connector wiring, the relevant model is the E3Z-LS88. Operating temperature is specified from -25 to 55°C, while storage extends from -40 to 70°C. Reversed power-supply polarity protection, output short-circuit protection, and mutual-interference prevention are included. PBT is listed as the housing material. The 2 to 80 mm range supports sensing where the selected target position remains relatively close to the sensor face. Its specification also suits requirements for an Omron PNP BGS sensor, Omron 80 mm photoelectric sensor, and M8 distance sensor. For a related PNP connector model with a wider 20 to 200 mm range, see E3Z-LS86.
