Datasheets
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.
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.
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.
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.
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.
