ET4-E4228 Application Field and Working Principle

Optical sensors are an important and integral part of many industrial systems. The ET4-E4228 photoelectric optical sensor, which is one of the latest industrial optical sensors developed by Eltako in Germany, is used to detect the presence of a human, an animal, or an object within its detection range. It is often used in automated control systems to ensure maximum safety and for motion sensing.

What Are the Applications of ET4-E4228 Photoelectric Optical Sensor?

The ET4-E4228 photoelectric optical sensor has a wide range of applications and can be used in different industrial fields for various tasks. It is ideal for areas where motion sensing, object detection, and presence detection are important, such as in the following fields:

• Security systems: The ET4-E4228 can be used to detect intruders or movement within an area. Its detections range up to three meters (nine feet) so it is suitable for larger applications.
• Automation: The ET4-E4228 can be used in automated control systems to detect the presence of an object or person and activate a switch, which can be used to control the flow of goods and services.
• Medicine: The ET4-E4228 can be used in medical settings to detect the presence of a person, such as in a hospital bed or an x-ray machine. It can also be used to detect movement, which can be used to ensure that patients are not left unattended for extended periods of time.

What Is the Working Principle of ET4-E4228 Photoelectric Optical Sensor?

The ET4-E4228 photoelectric optical sensor uses an infrared light source to detect the presence of a human, an animal, or an object within its detection range. The sensor has two terminals, a power terminal and a control terminal, which are connected to the power and control circuits of the system using electrical leads. The control terminal is connected to an output device such as a switch or a servo motor.When the ET4-E4228 detects a target object or person within its detection range, the infrared light source is activated and the signal from the sensor is sent to the connected output device. This signals the output device to activate, which can either signal an alarm or activate a switch or other device as programmed. The ET4-E4228 has an adjustable detection range, which allows it to be adjusted for different areas and applications.

Conclusion

The ET4-E4228 photoelectric optical sensor is an important industrial optical sensor developed by Eltako in Germany. It is widely used for motion sensing, object detection, and presence detection in many industrial applications. Its working principle is based on the detection of infrared light from an object or person within its detection range, which is then sent to an output device. This output device can then be used to control other systems or to trigger an alarm.
