It switches PNP outputs up to 100 mA, selectable for light-on or dark-on operation. The 1 msec response time suits high-speed part detection on conveyor or pick-and-place stations. Diffuse sensing at 100 mm means the sensor detects objects within that range without a separate reflector — the target itself reflects the infrared beam back. The wide-beam feature spreads the emitted light, so it catches targets with irregular surfaces or slight misalignment, reducing false negatives on a mixed-product line. IP67 sealing means the PBT housing withstands washdown and dust ingress — rated for food-and-bev or wet machining environments. The right-angle face orientation and 2 m prewired cable simplify mounting in tight panel or machine frames. The 12-24V DC supply and PNP output are standard for most PLC digital inputs. The 100 mA load current covers direct drive of small relays or indicator lamps without an interposing interface.","metaTitle":"Omron E3ZD81 Photoelectric Sensor, Diffuse, PNP, 100 mm","metaDescription":"Omron E3ZD81 diffuse photoelectric sensor, PNP output, 100 mm sensing range, 12-24V DC, IP67, CE.
