Proximity sensors are devices used to detect the presence of nearby objects without any physical contact with the target. One of the most widely used proximity sensors in industrial settings is the EI1808TBOPL. This article will discuss the application fields and working principle of this sensor.

Application Fields

The EI1808TBOPL sensor is designed to detect the presence of metallic and non-metallic objects. It has a wide range of application fields including:

• Filling line operations
• Automotive assembly and paint operations
• Piston and shaft machining
• Medical equipment manufacturing
• Food and beverage processing
• Robotics inspection
• Paper and cellulose manufacturing
• Textile and clothing production
• Power generation and transmission

The EI1808TBOPL sensor has excellent sensing performance, making it a popular choice for use in industrial applications. Its sensing range is adjustable between 1mm and 8mm, covering a wide variety of applications.

Working Principle

The EI1808TBOPL uses a three-terminal operating principle. It consists of an oscillator circuit, a sensing element, and a control circuit. The oscillator circuit produces an oscillation signal, which is then sent to the sensing element. The sensing element is composed of a ferromagnetic material, which is positioned above the switch contacts. When a nearby metallic or non-metallic object is detected, the switch contacts change state, causing the oscillation signal to stop. This change in state is then registered by the control circuit, which in turn sends a signal to the output port.

The EI1808TBOPL is designed to operate in a range of temperatures, from -25°C (-13°F) to +80°C (176°F). The sensing range is adjustable between 1mm and 8mm, with a maximum switching capacity of 0.3mA at 12V DC. This makes it suitable for a variety of applications where accuracy and long-term reliability are critical.

Conclusion

The EI1808TBOPL is a versatile and reliable three-terminal proximity sensor that is widely used in industrial settings. It is designed to detect the presence of metallic and non-metallic objects in a range of temperatures. It has a wide range of applications, including filling line operations, automotive assembly and paint operations, piston and shaft machining, medical equipment manufacturing, food and beverage processing, robotics inspection, paper and cellulose manufacturing, textile and clothing production, and power generation and transmission. The working principle of the EI1808TBOPL involves an oscillator circuit, a sensing element, and a control circuit, which are used to detect a change in the switch contacts caused by the presence of an object and send a signal to the output port. This sensor is a reliable choice for industrial operations where accuracy and long-term reliability are essential.
