OMRON has launched a new E3AS-HL CMOS laser sensor with industry-first sensing technology which significantly improves detection capability. Reliable detection of difficult-to-detect targets helps eliminate the need for time-consuming installation design and adjustment at equipment commissioning.
A CMOS laser sensor is a type of reflective photoelectric sensor which comprises a laser emitter and CMOS image receiver and uses triangulation detection techniques.
Detection by means of conventional reflective photoelectric sensors is affected by the target’s colour, material, or surface. Human experience and skills are required to design and adjust the sensor installation for each target. This issue often arises in the automotive and food industries where various targets with complex shapes and glossy surfaces are detected.
The new laser sensor can reliably detect targets which cannot be detected with reflective photoelectric sensors. Its industry-first sensing algorithm reaches high-speed sampling at 10 000 times per second and OMRON’s unique accumulation processing increases sensitivity by amplifying the slightest amount of light reflected from the target. The manufacturing technology adjusts the receiver lens position in the sensor to a µm level, enabling reliable detection of any target, irrespective of colour, material, or shape.
These technologies allow the E3AS-HL sensor to reliably detect curved and irregular shaped and/or glossy parts as well as multi-coloured and glossy food and packages. The sensor can be used where reflective photoelectric sensors were used and helps significantly reduce the time required to adjust the sensor installation position and angle and the threshold values.
- Reliable detection of difficult objects reduces equipment design and commissioning time
- Increased equipment design flexibility reduces design time
- Antifouling coating on sensing surface ensures stable operation even in harsh environments (patent pending)
- OLED display and teaching enable easy, quick, and optimal setting
