Omron Industrial Automation E3AS-HF ToF Laser Sensors
Omron Industrial Automation E3AS-HF ToF Laser Sensors are Time of Flight (ToF) photoelectric sensors that achieve stable detection of difficult-to-sense targets up to 6m away. The E3AS-HF series is equipped with a patent-pending high-sensitivity photodiode and can reliably detect targets with low light reflectivity. This low-light detection makes the sensors suitable for the detection of dark targets on a dark background or curved and shiny surfaces. A unique sensing algorithm means the Omron Industrial Automation E3AS-HF provides superior detection of targets at harsh angles, allowing for greater flexibility in machine design or retrofitting a sensor into existing setups.The E3AS-HF series is ideal for continuous level detection applications, such as determining stack height, overflow, or run-out detection of opaque liquids or goods, or for detection of shiny, dark, or curved surfaces at long ranges. With a 6m sensing range, this sensor can be mounted away from moving robots, workers, or other dangerous equipment that often damages sensors and contributes to unexpected downtime.
With an easy-to-read display, bright visible indicators, IO-link compatibility, and a set-up menu equipped with five different language options, users can cut down costly configuration and setup time while maintaining stable detection of their most difficult-to-sense objects.
