The Omron E3Z-G81-M3J Photoelectric Sensor uses a grooved sensing method to detect opaque targets as small as 1.5 mm, with a fixed 25 mm detection range. Its 940 nm infrared LED ensures stable performance even under varied lighting conditions. With PNP output and a power supply of 12 to 24 VDC, it is well-suited for compact sensing requirements in industrial automation lines such as sorting, labeling, or assembly processes.
A pre-wired M8, 4-pin connector allows fast integration into modern control systems. The Light-ON/Dark-ON selectable mode provides versatile operation, while the orange status indicator confirms active detection. With a 1 ms response time, it excels in dynamic applications, reliably detecting fast-moving or small-sized components without lag or false triggering.
Constructed with durable ABS housing and rated IP64, the E3Z-G81-M3J is resistant to dust and splash exposure. It features comprehensive protection circuits for reverse polarity, short circuits, and mutual interference prevention, ensuring long-term reliability in harsh factory environments.
