The sensor is suitable for applications ranging from temperature to flow and pressure measurements.Furthermore, the HL18G-N1G3BL is one of the most widely used optoelectronic sensors in automotive, consumer electronics, and robotics industries. It is used to detect objects, and also to provide data and feedbacks to control systems.

Working Principle

The HL18G-N1G3BL optical sensor works by collecting light from an object using a photosensitive element, usually a photo resistor or photodiode. When light hits the light sensor, its resistance changes. This change in resistance is converted to voltage by electronics built into the sensor.The HL18G-N1G3BL optical sensor relies on the differential photodiode principle for its operation. This technique employs two photodiodes which are connected in opposition. When a light source shines on the two photodiodes, the current flowing through the sensor is determined by the amount of differential light intensities between the two photodiodes.This type of optical sensor is also capable of operating on a dual signal principle. In this configuration, the HL18G-N1G3BL can detect both reflected and transmitted light. The reflected light signal is used to measure the distance to an object, while the transmitted light signal is used to measure object size and shape. This feature is especially useful in robotics and pick-and-place applications.

Conclusion

The HL18G-N1G3BL is a reliable and versatile optical sensor which has found widespread applications in industrial automation and robotics markets. Employing a differential photodiode design, it is capable of providing accurate measurements even in harsh environments. It also has the capability of dual signal operation, allowing it to detect both reflected and transmitted light, making it an invaluable tool for robotics and pick-and-place applications.
