Omron?s compact E3FA/E3RA/E3FB/E3RB series of photoelectric sensors is simple and quick to mount, as well as easy and intuitive to set-up. The large and robust adjuster makes life much easier for installers to adjust the sensor, as does the bright, high-power red LED, which is clearly visible for easy alignment, even over longer distances. Similarly, the sensor?s LED status indicator can be viewed from long distances and wide angles.
