OMRON introduces long-range laser sensor

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

Launched by OMRON Industrial Automation the E3AS-HF is 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 .05 to 6 metres 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.

The ToF method measures distance based on elapsed time, making detection unaffected by colour 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 minimising 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 maximises 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. With the built-in real-time temperature element, the sensor reduces characteristics variation and ensures stable sensing.

Thanks to its extended range and wide-angle detection, the E3AS-HF can be installed further from moving machinery, minimising collisions, misalignment, and downtime. Its robust IP67/IP69K-rated die-cast aluminium housing and antifouling coatings provide durability in harsh conditions, including dust, moisture, and high-pressure cleaning.The post OMRON introduces long-range laser sensor first appeared on Warehouse & Logistics News.
