Features
E3AS-HL for multi-lane conveyor lines of targets with curved surface
Stably detects cans and plastic bottles without reflectors
Left image: Retro-reflective sensors are used to detect poorly reflective curved surfaces of cans and transparent plastic bottles, but securing installation space for reflectors on multi-lane conveyor lines is difficult.
Right image: The E3AS-HL Sensor, a reflective model capable of detecting the slightest change in the incident light level or distance, can stably detect cans and plastic bottles without reflectors.
E3AS-HL for complex-shaped, colored, patterned or glossy targets
Left image: With spot beam, detection is unstable since the reflected light does not reach the sensor depending on the profile of the target surface. With the line beam of the E3AS-HL Sensor, detection is less affected by the profile of the surface since the reflected light reaches the sensor from any part of the surface.
Right image: Detection is prone to be unstable because color, pattern or reflectivity affects the sensing distance. The E3AS-HL Sensor is less likely to be affected by them, providing stable detection even when packaging materials change.
E3AS-F for long-distance sensing on converging and diverging lines
No reflector is required to design long-distance sensing unaffected by color or material of targets
Although retro-reflective sensors are used for long-distance sensing in converging and diverging lines, it is difficult to find installation space for reflectors.
The E3AS-HL Sensor, a reflective model with long sensing distance, does not require reflectors. Moreover, it is less likely to be affected by color even from long distances.
TOF method enables detection of various workpieces on the conveyor line
With conventional photoelectric sensors, prior evaluation was required for each workpiece to be detected. E3AS-F Sensors detect workpieces varying in colors and materials by the set distance. This helps reduce evaluation and adjustment time. Also, they do not detect workers working near the line by mistake.
Antifouling coating prevents contamination on the sensing surface
Dirty sensing surface can cause false detection due to the principle of photoelectric sensors. E3AS Series with the antifouling coating on the sensing surface, which is the industry’s first, prevents water droplets, oil, and dust from sticking to the sensing surface, and keeps the lens from fogging as well. Therefore, the coating prevents contamination on the sensing surface in environments where oil or dust scatters, or steam generates. False detection and cleaning frequency are also reduced.
Laser welding technologies for different materials/metals for increased environmental resistance
The sensor case is made of stainless steel (SUS316L). Omron’s two unique technologies, laser welding technology for different materials and laser welding technology for metals, enhanced the sealing and adhesion between the stainless steel and resin.
Laser welding technology for different materials
It is a technology to weld different materials, resin and metal, using laser beams. Small holes are bored into the metal case, then melt the resin part by laser. The melted resin fills the holes for secure sealing and adhesion.
Laser welding technology for metals
The metal case and cover are welded by a laser beam to seal the gaps. This provides higher airtightness compared to adhesives, keeping out water, oil and other substances to reduce failures.
