The CY-21 is an industrial-grade, photoelectric-type optical sensor. It is capable of detecting objects in a wide range of lighting conditions and offers powerful performance in most industrial applications. The device is typically used for detecting objects such as switches, cylinders, and conveyors in industrial settings. It can also be used for process control, safety systems, and distance sensing applications.

The main components of a CY-21 type optical sensor consist of an internal light source, an external light detector, and an output signal conditioning circuit. The internal light source is usually a combination of LEDs and/or infrared light emitters. These generate a light beam which travels to the instrument’s output. The external light detector is a photodiode that receives the light beam, which is further converted into a digital signal. This digital signal is then sent to the output signal conditioning circuit which amplifies and converts it into an analog signal.

When the optical sensor is connected to an external control system, the output signal is used to trigger an action. This could be to close a valve, adjust the speed of a motor, or trigger an alarm. Depending on the application, the output signal can be conditioned differently to provide the desired output. For example, in safety applications the output signal can be configured to offer a fail-safe shut off upon detection of an object.

The CY-21 optical sensor works by emitting a light beam that is detected by a photodiode after bouncing off an object in its vicinity. The photodiode then converts the light into a digital signal and sends it to the output signal conditioning circuit. This output is then sent to the connected control unit. Typically, the output is an analogue signal, but in some advanced models, the output is provided in pulse-width modulation format.

The CY-21 has proven itself very useful in various industrial applications due to its power, performance, and wide range of detection. It is typically used in process control systems, safety systems, and distance-sensing applications. Additionally, the device can be used in hazardous environments due to its reliable performance and safety features. The sensor is also known for its cost-effectiveness, flexibility, and scalability, which makes it an attractive option for engineers and system integrators.

In summary, the CY-21 is an industrial-grade, photoelectric-type optical sensor used for detecting objects in a wide range of lighting conditions. It is typically used in process control systems, safety systems, and distance-sensing applications. The main components of the device consist of an internal light source, an external light detector, and an output signal conditioning circuit. The light beam generated by the internal light source is capable of bouncing off an object to be detected by an external light detector. The output signal can then be used to trigger an external action. The CY-21 is cost-effective, flexible, and scalable, making it a great option for most industrial applications.
