Optical sensors have become increasingly essential for industrial applications due to their ability to accurately measure and monitor parameters such as displacement, angle, velocity, and acceleration with a wide dynamic range. The E3RA-DN21 is a high-performance photoelectric sensor that is particularly suited for these industrial applications. This article will describe the application field and working principle of the E3RA-DN21.

Application field of the E3RA-DN21

The E3RA-DN21 photoelectric sensor is designed primarily for industrial applications and provides an extremely wide dynamic range, making it ideal for detecting, analyzing, and controlling a wide variety of objects. It can detect objects regardless of their size, shape, color, or even material.

The sensor is capable of accurately detecting objects over long distances, and its high-precision control of irradiation intensity ensures reliable operation in harsh environmental conditions, such as high levels of dust and vibration. Its built-in LED and detection head make it an excellent choice for surface inspection applications.

The E3RA-DN21 is also a great choice for applications that require multiple outputs, such as counting or sorting applications, as it can provide both analog and digital outputs simultaneously.

Working Principle of the E3RA-DN21

The working principle of the E3RA-DN21 is based on the process of measuring light intensity with a photodiode. It uses an LED as the light source, and the detector is a PSD (position sensitive detector) to measure the light intensity. The sensor can detect objects of different sizes, shapes, and colors based on the light intensity of the photodiode.

When the light from the LED strikes an object, the detected light intensity is measured with the photodiode, which is then converted to a signal voltage. When there is no object present, the detector does not receive any light and its output voltage remains at zero. When an object is present, the output voltage increases and it can be used to trigger an alarm or to control other external equipment.

The E3RA-DN21 also features adjustable brightness and sensitivity settings, allowing for greater precision and accuracy when detecting objects. This makes it an excellent choice for applications that require exact measurements, such as precise sorting, angle measurement, position detection, and surface inspection.

The E3RA-DN21 is an excellent choice for a wide variety of industrial applications, due to its accuracy, versatility, and wide dynamic range. Its ability to detect objects regardless of their size, shape, color, or even material, makes it a great choice for any application that requires accurate measurements over long distances or in harsh environmental conditions.
