Omron E3Z-D87 Photoelectric Sensor
Omron E3Z-D87 is a diffuse-reflective photoelectric sensor for direct object sensing across a distance of up to 1 m. Its 870 nm infrared LED sends light toward the target, allowing the returned optical signal to establish the switching state without a separate reflector. The PNP output transfers this state to compatible industrial control equipment, while Light-ON or Dark-ON operation can be selected according to the required machine logic. The sensor operates from 12 to 24 VDC and uses an M8 connector for detachable wiring. Current consumption is specified at 30 mA maximum, response time at 1 ms maximum, and a one-turn adjuster supports sensitivity setting. Within the E3Z Series, the E3Z-D87 provides the 1 m PNP configuration for M8 diffuse sensors across Omron Automation Products.

The Omron E3Z-D87 Photoelectric Sensor uses diffuse-reflective sensing for direct object sensing across a distance of up to 1 m. Its 870 nm infrared LED directs light toward the target, and the returned optical signal is evaluated without requiring a separate reflector. The PNP output transfers the switching state to compatible industrial control circuitry, while Light-ON or Dark-ON operation can be selected according to the required logic. The sensor operates from 12 to 24 VDC and uses an M8 connector for detachable wiring. Current consumption is specified at 30 mA maximum, response time at 1 ms maximum, and a one-turn adjuster supports sensitivity setting. Ambient-light resistance reaches 3,000 lx under incandescent light and 10,000 lx under sunlight.
For an Omron long-range diffuse sensor requiring PNP output and an M8 connection, the applicable model is the E3Z-D87. Operating temperature extends from -25 to 55°C, while storage covers -40 to 70°C without icing or condensation. Insulation resistance is specified at 20 MΩ minimum at 500 VDC, and dielectric strength is 1,000 VAC for one minute. Reverse supply polarity, output short-circuit, mutual-interference, and reversed-output polarity protection are included. Its PBT construction supports compact machine mounting. The specification also suits searches for an Omron 1 m PNP photoelectric sensor and Omron M8 infrared sensor. For a shorter 100 mm PNP diffuse model with the same M8 connector format, see the E3Z-D86.
