Omron E3Z-B87 Photoelectric Sensor
Omron E3Z-B87 is a retro-reflective photoelectric sensor without the MSR function, specified for clear plastic bottle sensing across a 500 mm to 2 m range. A 660 nm red LED establishes the optical path toward the reflector, while the PNP output communicates the switching state to compatible industrial control inputs. Selectable Light-ON and Dark-ON operation supports different machine-control requirements. The sensor operates from 12 to 24 VDC and uses a standard M8 connector for electrical connection. Current consumption is specified at 30 mA maximum, response time is 1 ms maximum, and a one-turn adjuster provides sensitivity setting. Within the E3Z Series, the E3Z-B87 provides the long-range PNP connector configuration. Related reflector-based bottle sensors can be explored across Omron Industrial Products.

The Omron E3Z-B87 Photoelectric Sensor uses retro-reflective sensing without the MSR function for clear plastic bottle sensing from 500 mm to 2 m. Its 660 nm red LED establishes the optical path between the sensor and reflector, while the PNP output transfers the switching state to compatible industrial control equipment. The output supports up to 100 mA load current and a maximum load supply voltage of 26.4 VDC. Light-ON or Dark-ON operation can be selected to suit the required logic. The sensor operates from 12 to 24 VDC, consumes up to 30 mA, and provides a 1 ms maximum response time. A standard M8 connector and one-turn sensitivity adjuster support setup and electrical integration.
For an Omron PNP retro-reflective sensor requiring an M8 connector and a 2 m maximum working range, the relevant model is the E3Z-B87. Ambient-light resistance reaches 3,000 lx for incandescent light and 10,000 lx for sunlight. Operating temperature extends from -25 to 55°C, with storage from -40 to 70°C without icing or condensation. Reverse supply polarity, output short-circuit, mutual-interference, and reversed-output polarity protection are specified. PBT and modified polyarylate are listed as construction materials. Its specification also matches searches for an Omron PNP bottle sensor and Omron 2 m M8 photoelectric sensor. For another PNP connector variant with the same stated working range, see the E3Z-B86.
