Omron E3Z-D81 2M Diffuse Photoelectric Sensor 12-24 VDC PNP Light-ON/Dark-ON 100 mm

The Omron E3Z-D81 2M is a compact and reliable diffuse-reflective photoelectric sensor ideal for industrial automation, machine control, and object detection tasks. Using a red LED and a diffuse sensing method, this sensor detects objects at distances up to 100 mm without the need for a reflector. It operates from 12–24 VDC and offers a PNP output with Light-ON/Dark-ON selectable modes, providing flexible integration with PLCs and control systems. The 2 m pre-wired cable simplifies installation in production lines and control panels. With a rugged PBT housing and IP67 ingress protection, the E3Z-D81 performs reliably in harsh industrial environments.
