The Omron Slot Sensor EE-SX671 is part of the reliable Omron EE-SX series, known for compact design and accurate detection. With a fixed 5 mm slot and an integrated infrared LED (940 nm), this sensor uses a throughbeam method to detect small parts, edges, or labels in motion. Its L-shaped housing allows efficient installation even in narrow spaces.
Designed for photoelectric sensor applications, it supports 5–24 VDC operation and delivers selectable Light-ON/Dark-ON functionality with NPN output. The connector-type design and low power usage (12 mA max) ensure fast integration and reliable control. Built-in short-circuit protection, PBT plastic body, and IP50 rating make it suitable for moderate industrial use including printers, labeling systems, and miniature conveyors.
The photosensor Omron EE-SX671 delivers precise and fast detection performance under varying light and temperature conditions. It handles vibrations (100 m/s²) and shocks (500 m/s²), supporting durability in active production lines. Its use in edge positioning, gear tracking, and compact embedded systems highlights its versatility. Similar models like the Omron EE-SX670 offer variations in slot size for different needs.
