E3ZM-B81T 2M

Optical Sensors - Photoelectric, Industrial Use

Optical sensors are widely used in the field of industrial automation. These sensors often contain photosensitive elements, such as photodiodes or phototransistors, which detect light and generate an electrical signal in response. One such optical sensor is the E3ZM-B81T 2M, which is used in industrial applications such as factory automation and object detection. This article will explain the application field and working principle of the E3ZM-B81T 2M.

Application Field

The E3ZM-B81T 2M is ideally suited for factory automation and production line assembly applications, as it is able to detect the presence of an object quickly and reliably. It can be used to sense distance and determine whether an object is in the correct position. Additionally, it can be used for object detection, marking the difference between one object and anther, by sensing variations in light intensity.

The E3ZM-B81T 2M is also suitable for use in safety equipment, due to its ability to detect the presence of an object. By installing an E3ZM-B81T 2M in a door, it can detect the presence of any object that might obstruct the path of the door, preventing injury or damage.

Working Principle

The E3ZM-B81T 2M uses a photodiode to detect light. The photodiode is composed of two layers of semiconductor material, with a junction between them. Electrons move from one layer to the other when illuminated by light of a certain wavelength, producing an electric current. This current is then used to detect the presence of an object.

The photodiode works similarly to a normal electric switch. When an object blocks the light, the current decreases and the switch is triggered. When the object is removed, the current increases and the switch is turned off. The E3ZM-B81T 2M also has a detection range, allowing it to detect larger objects from a distance. The sensitivity of the detector can also be adjusted, allowing the user to customize it for their particular application.

Conclusion

The E3ZM-B81T 2M is a versatile optical sensor, ideal for applications such as factory automation and object detection. It is based on a photodiode, which generates an electric current in response to incoming light. This current can then be used to detect the presence or absence of an object, and to differentiate between different objects.
