Omron E3Z-LS81 0.5M Photoelectric Sensor
Omron E3Z-LS81 0.5M is a distance-setting photoelectric sensor designed for object sensing 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 includes a 0.5 m pre-wired cable for short fixed wiring. Current consumption is specified at 30 mA maximum, while response time is 1 ms maximum. The PNP configuration distinguishes this model from comparable NPN versions. Within the E3Z Series, the E3Z-LS81 0.5M supports the PNP distance-setting sensor range across Omron Industrial Products.

The Omron E3Z-LS81 0.5M Photoelectric Sensor uses distance-setting sensing across a specified 20 to 200 mm range with PNP output. A 670 nm red LED provides the optical source, while the output sends 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 switching logic, while response time is specified at 1 ms maximum. A 0.5 m pre-wired cable provides short fixed wiring between the sensor and associated connection point. PBT is listed for the case, while denatured polyarylate is specified for the optical section. The PNP configuration distinguishes this version from comparable NPN distance-setting models.
For an Omron PNP distance-setting photoelectric sensor requiring a 200 mm maximum range and short pre-wired connection, the relevant model is the E3Z-LS81. Its 12 to 24 VDC operating supply, 30 mA maximum current consumption, and selectable output logic support integration with compatible PLC and machine-control inputs. The stated range provides the available target position for this particular listing. Its specification therefore suits requirements for an Omron PNP photoelectric sensor, Omron 200 mm distance sensor, and 0.5 m pre-wired sensor. For another E3Z-LS81 configuration using a 2 m cable with a background-suppression arrangement, see E3Z-LS81 2M.
