Optical Sensors are commonly used in many industrial and commercial applications. These sensors measure the intensity of light to detect and register the presence of an object or its position. The available types of optical sensors are Photoelectric, Industrial, and Infrared.

E3FB-TN22, one of the most commonly used Photoelectric Sensors, is a reliable sensing device primarily designed for detecting and sensing the presence or absence of objects of any shape. It is capable of sensing the light reflected by the surface of the object accurately for switch or control purposes. It is widely used in various industrial settings such as robotics, medical imaging, and machine vision, among others.

Application field

E3FB-TN21 is used in various applications which require accurate detection of objects. It is mostly used for industrial automation applications such as robotics, packaging lines, sorting and counting machines, conveyor systems, and automated sorting and counting machines. It can also be used for security purposes such as motion sensors, intruder alarms, and access control systems. Additionally, it is also used in medical imaging and machine vision applications. With its flexible configurability, it is suitable for applications such as automated production lines, production inspections, and motion monitoring.

Working principle

The working of the E3FB-TN21 sensor is based on the recognition of objects and their detection. It works by emitting modulated light, usually an infrared beam, in response to a signal from its controller system. In response, the detector in the sensor will detect the difference in wavelength of the wavelength striking the object as compared to the wavelength leaving it. This difference in wavelength is what the E3FB-TN21 sensor uses to identify and detect objects.

The E3FB-TN21 utilizes an optical receiver and a phototransistor to detect the reflected light from the object’s surface. The microprocessor in the sensor then processes the data, and the sensor is able to detect the presence or absence of a targeted object. The integrated circuit present in the sensor is used to identify and analyze the information received from the optical receiver. This enables the sensor to detect the presence of any object accurately.

The E3FB-TN21 provides an output of either NPN (low-sink) or PNP (high-sink) controls. The output is either high for when the presence of an object is detected or low for when the absence of an object is registered. Additionally, the sensor also includes an LED indicator, which indicates its presence and detection accuracy.

The E3FB-TN21 is a reliable and cost-effective photoelectric sensor that is widely used in various industrial applications for accurate detection of objects. It is also extremely energy-efficient, durable, and equipped with advanced features that make it suitable for industrial and commercial applications. With its ideal design, high accuracy, and flexibility, the E3FB-TN21 is one of the most reliable sensors available on the market today.
