Omron E3Z-T87 Photoelectric Sensor
Omron E3Z-T87 is a through-beam photoelectric sensor designed for object sensing across a specified distance of 30 m. The sensing arrangement uses the E3Z-T87-L emitter and E3Z-T87-D receiver, with an 870 nm infrared LED establishing the optical path between them. The PNP output communicates the switching state to compatible machine-control circuitry, while selectable Light-ON and Dark-ON operation supports different switching requirements. The sensor operates from 12 to 24 VDC and uses a standard M8 connector for electrical integration. Total current consumption is specified at 35 mA maximum, while response time is 2 ms maximum. An opaque target of 12 mm diameter minimum is specified. The E3Z-T87 provides connector wiring within the 30 m PNP through-beam sensor range across Omron Industrial Products.

The Omron E3Z-T87 Photoelectric Sensor uses through-beam sensing across a specified distance of 30 m. The optical arrangement includes the E3Z-T87-L emitter and E3Z-T87-D receiver, with an 870 nm infrared LED establishing the beam between them. An opaque target of 12 mm diameter minimum is specified. The PNP output supports a load supply voltage up to 26.4 VDC and load current up to 100 mA. The units operate from 12 to 24 VDC and consume 35 mA maximum in total, with 15 mA maximum specified for the emitter and 20 mA maximum for the receiver. Light-ON or Dark-ON operation is selectable, while operate or reset time is 2 ms maximum. A one-turn adjuster supports setup, and the standard M8 connector provides the electrical interface.
For an Omron long-range PNP through-beam sensor requiring a 30 m sensing distance and connector wiring, the relevant model is the E3Z-T87. Operation and stability indicators provide visual status, while the emitter includes a dedicated power indicator. Operating temperature is specified from -25 to 55°C under the stated conditions, with storage extending from -40 to 70°C. Ambient-light resistance is specified at 3,000 lx for incandescent illumination and 10,000 lx for sunlight. Reversed power-supply polarity protection, output short-circuit protection, and reversed output-polarity protection are listed. PBT and modified polyarylate are specified among the materials. For a related 30 m PNP model using 2 m pre-wired cables, see E3Z-T82 2M.
