ET1820 photoelectric sensors are widely used in industrial automation applications such as material process control, open/close monitoring, material positioning, fault detection, etc. In general, they can detect the presence of an object and can also detect the position of an object. They are used in a variety of fields such as automotive, home appliances, robotics, etc.

The ET1820 photoelectric sensor functions mainly by transmitting an infrared light beam and receiving its reflection, which is then used to identify and indicate presence or absence of an object. This is referred to as a "non-contact" system, as the light beam is used to detect objects without actually touching them. It includes a light emitter that produces an infrared light beam, which is then focused to a specific area, and a receiver that captures this light when it reflects off an object.

The sensitivity of this photoelectric sensor can be adjusted by using the potentiometer located on the device. This is to ensure the ET1820 sensor is accurately detecting objects in its field of view. The range of the light beam is between 0 and 250cm. This sensor also has response time, which is the time it takes between detection and the response signal being returned.

The ET1820 photoelectric sensor also has the ability to detect the position of an object. This is done by adjusting the angle of the emitted light beam. As the object moves in the field of view, the angle of the emitted light beam must be adjusted so that the beam is always pointing in the direction of the object. This is done using an internal motor, which adjusts the angle with respect to the position of the object.

This ET1820 photoelectric sensor has a wide range of applications in industrial automation sectors. It is used for material process control, open/close monitoring, material positioning, fault detection, etc. The photoelectric sensor is extremely precise and reliable, and can be used in a variety of fields, from automotive to home appliances and robotics. Its ability to accurately and quickly detect objects and their position makes it a valuable tool for industries that rely on automated production.
