The Omron EE-SPX843 is a compact grooved type photomicrosensor designed for precise object detection in narrow slots. It features a 3.6 mm slot width and uses modulated infrared light to minimize interference from ambient sources, ensuring reliable operation in industrial settings.
This through-beam sensor operates in Light-ON mode and provides an NPN voltage output, with a residual voltage of just 0.4 V at 10 mA. With a maximum current consumption of 15 mA (average) and 50 mA (peak), it supports quick and efficient signal transmission. The red LED indicator provides a visual status for easy monitoring during setup and operation.
Housed in durable polycarbonate and rated IP50, the EE-SPX843 performs well in temperatures from -10°C to 55°C. It is ideal for applications like part detection, component presence sensing, and position confirmation in compact machinery.
