Omron EE-SX871 Micro Photoelectric Sensor NPN Compact

Omron EE-SX871 Slot Sensor

The Omron EE-SX871 is a compact slot sensor designed for detecting small objects, labels, and parts in industrial automation applications. This through-beam sensor features a 3mm slot width, making it ideal for detecting small targets such as electronic components, small mechanical parts, and paper labels. The EE-SX871 uses infrared LED as the light source and provides reliable detection regardless of target color or material, as long as the target can block or interrupt the light beam. The sensor features an NPN open-collector output for connection to PLCs and other control devices. The compact design with resin body ensures reliable operation in industrial environments. The EE-SX871 is widely used in electronics manufacturing for component detection, printing machines for paper registration, and packaging equipment for label sensing. The sensor operates on 5-24 VDC wide voltage range, providing flexibility in system design.
