The Omron Broad Slot-type Photomicrosensor EE-SPX403N is engineered for accurate and fast detection of small opaque objects in industrial applications. With a slot width of 13 mm and a differential distance of 0.05 mm, it ensures reliable sensing of targets as small as 2.2 Γ 0.5 mm. Its red LED indicator and NPN voltage output simplify visual monitoring and system integration.
Powered by a 12β24 VDC supply, the EE-SPX403N supports load currents up to 80 mA and includes both power and output reverse polarity protection. Its infrared LED (pulse lighting, 940 nm) delivers stable detection performance under variable lighting conditions up to 3,000 lx. With a compact 4 g polycarbonate body and IP50 rating, it resists shock, vibration, and ambient interference.
Installation is streamlined with a special connectorβno soldering requiredβmaking the EE-SPX403N ideal for modular assembly lines and automation panels. It operates between -10Β°C and 55Β°C and offers a minimum response frequency of 100 Hz. Learn more browse similar Omron photoelectric sensors on IndMALL.
