It utilizes a combination of an infrared emitter and a receiver, and offers several options for the selection of different sensitivity and viewing angles. The device is also equipped with adjustable outputs and can be used for the input signal of any control device.The ET4-F2238 is designed to be used in the context of production line automation, particularly for the detection of objects such as packages, boxes, bearings, and other moving parts in order to detect their presence and further in process automation. It is also suitable for applications where reliability and safety are a must, such as doorways, material handling, and other hazardous environments.The basic working principle behind the ET4-F2238 is the use of an emitter diode, which emits infrared light, and a receiver diode, which receives the infrared light emitted by the emitter. The emitter and receiver are mounted so that they are on opposite sides of the object to be detected. When an object passes between the emitter and receiver, the infrared light is reflected, thereby sending the signal to the receiver diode and providing an output.The ET4-F2238 is available with various sensitivity levels and viewing angles, allowing it to be used in a variety of applications and environments. It is also capable of detecting objects at distances of up to 40 cm (15.7 in). Furthermore, the device can be adjusted in order to meet specific requirements, such as the ability to differentiate between two objects of different colors.The ET4-F2238 delivers excellent detection accuracy and reliability. It has an adjustable timing delay, allowing for the delay of up to 8 seconds, thus ensuring the safe operation of the device. The device also offers an adjustable impulse length, giving the user the ability to customize the impulse length according to the application. Finally, the ET4-F2238 is highly resistant to electromagnetic interference.Overall, the ET4-F2238 is an excellent optical sensing device suitable for a variety of industrial applications. It offers reliable and accurate object detection, adjustable outputs, adjustable sensitivity and viewing angles, adjustable impulse timing, and superb resistance to electromagnetic interference. As such, it is a great choice for any industrial application requiring reliable and accurate object detection.
