The E3AS-HF Time-of-Flight (ToF) sensor offers reliable detection from 5 cm to 6 m with a unique angle characteristic for greater installation flexibility
OMRON Industrial Automation launches the E3AS-HF, a long-range ToF sensor designed for stable and precise detection in demanding industrial environments where accurate object detection, positioning, and distance measurement are required. With a sensing range from 0,05 to 6 meters and a unique wide-angle characteristic of ±85°, the E3AS-HF photoelectric sensor ensures reliable operation regardless of colour, shape, or material—simplifying sensor selection and setup.
Three innovative technologies for superior sensing
The ToF method measures distance based on elapsed time, making detection unaffected by color or material. With the patented ultra-fast sampling at 10 billion times per second, it accumulates 10 million data points to generate a clear incident light waveform while minimizing noise. This enables the sensor to detect even low-reflective workpieces like black rubber from a long distance.
The high-frequency circuit technology, within the Laser Class 1 design, uses an extremely narrow pulse width that maximizes emission within safety limits. This eliminates the need for additional protective measures and allows for a compact and effective system setup. Another key feature, the high-sensitivity Avalanche Photodiode (APD) controlling algorithm, detects even minimal incident light.
Thanks to its extended range and wide-angle detection, the E3AS-HF can be installed further from moving machinery, minimizing collisions, misalignment, and downtime.
The OLED display offers intuitive operation, while fast 2ms response time and programmable I/O options, including IO-Link, make integration seamless. The built-in Automatic Mutual Interference Prevention function helps maintain stable operation even in applications where multiple sensors are used in close proximity.
