KT5G-2N1151 Application Field and Working Principle

Optical sensors are sensors that use light to detect the presence and absence of an object. Optical sensors are classified into several types according to the type of light used: photoelectric sensors, industrial sensors, and so on. Herein, the working principle and application fields of the KT5G-2N1151 photoelectric sensor are discussed.

KT5G-2N1151 Photoelectric Sensor Working Principle

The working principle of the KT5G-2N1151 photored LED photoelectric sensor is relatively simple. It uses a infrared sensing element to emit infrared light that is then reflected from an object, allowing it to detect the object’s presence or absence. When the infrared light is not detected by the sensing element, it indicates that the object is not present. The sensing element can take two different forms - reflective or transmittive. The reflective type is where the infrared light is emitted directly onto the object, and any reflected light is detected. The transmittive type is where the infrared light is sent through the object, and any light that is blocked or passed through is detected.

KT5G-2N1151 Sensing Element

The sensing element of the KT5G-2N1151 is an infrared LED, which emits invisible infrared light. The LED is usually mounted in a bar-shaped casing so that the light is emitted in a broad manner. The irradiated infrared light, in turn, is reflected from the object and is then detected by the sensing element – the infrared LED. An indicator LED is also mounted above the sensing element, allowing a visible light to be emitted along with the infrared light and informing the user as to the operational status of the sensor.

KT5G-2N1151 Application Fields

The KT5G-2N1151 photoelectric sensor can be applied to numerous applications in the industrial, commercial, and residential sectors. Photoelectric sensors are widely used in factories, plants, construction sites, and warehouses as a safety measure to ensure the safe operation of machinery. The sensor can also be used to detect the presence of objects at automated entrances and exits, allowing access to be granted or denied accordingly. In addition, the sensor can be used in automatic toll-collection systems and vending machines to detect if a user has paid or not. The photoelectric sensor is also used in motion-detection systems in the home, such as security systems or remote-control lighting and fans.

Conclusion

The KT5G-2N1151 is a photoelectric sensor that uses an infrared LED as its sensing element. It emits invisible infrared light which is then reflected from an object, allowing it to detect the object’s presence or absence. It can be applied to various applications in the industrial, commercial, and residential sectors. It is a reliable and cost-effective solution for detecting objects in a range of settings.
