Optical Sensors are devices that use light in order to detect the presence, absence, or change of an object within a certain environment. In the industrial environment, they are used to detect lack of lubrication, identify faulty parts, monitor machinery operations, and detect physical presence. Amongst the various types of optical sensors, FD-H20-21 falls under the Photoelectric and Industrial range.

FD-H20-21 is a low-cost and rugged optical sensor which offers a compact, reliable, and robust solution for a range of industrial applications. It is composed of a receiver element and a transmitter element, and can detect any objects which pass through the field of the optical beam. The receiver and the transmitter are connected by a cable, and both elements are housed within a hermetically sealed, robust housing. This sensor can be used in various applications such as machinery monitoring, process control and automation, environmental monitoring, and more.

The working principle of FD-H20-21 is based on the concept of photoelectricity, which involves the use of a light source and a photodetector. The light source is a light emitting diode (LED) which emit a beam of light. This light beam is directed towards the photodetector, which is a transducer that converts the light energy to electrical energy. When an object is present between the light source and the detector, the beam of light will be interrupted and the photodetector will detect this interruption. This output can be used to trigger an action, such as the turning on of a device or the triggering of an alarm.

In the industrial setting, FD-H20-21 is used to detect the presence of parts in a machine, detect a fault in a process, detect changes in the environment, and a lot more. Moreover, this optical sensor is capable of detecting objects regardless of their size, shape or color, making it an ideal choice for various industrial applications. This sensor can be used for applications where high reliability, repeatability and sensitivity are required. It also offers a wide range of adjustments depending on the application.

In conclusion, FD-H20-21 is a versatile and robust optical sensor that offers a range of advantages for industrial applications. Its working principle is based on the concept of photoelectricity, and it is capable of accurately detecting objects regardless of their size, shape or color. This sensor is suitable for applications where high reliability, repeatability and sensitivity are required, and is ideal for various industrial applications.
