The Omron EE-SPX401 is a precision-engineered slot-type photomicrosensor with a 3.6 mm grooved width for accurate object detection in small-scale industrial automation. It uses a modulated light source for stable operation and high immunity to ambient light interference.
This model operates in Light-ON mode and provides an NPN voltage output, delivering up to 80 mA of load current. The peak current consumption is just 50 mA, making it energy-efficient while maintaining consistent detection. A red LED indicator allows visual status confirmation, and its connector-type format simplifies quick installation and replacement.
With a polycarbonate housing and IP50 protection rating, the EE-SPX401 performs reliably in environments ranging from -10Β°C to 55Β°C. Itβs an ideal solution for part detection, edge sensing, and slot-based verification tasks in electronics assembly lines and compact machinery.
