Optical sensors are a broad category of sensors used to detect and monitor light levels, as well as to measure other physical parameters such as temperature, motion, and pressure. The CY-21-PN-J is a type of photoelectric optical sensor designed for industrial applications. The product is made by the Chinese company Changhe Motors, and it has been highly regarded for its accuracy, reliability, and low cost.

The CY-21-PN-J optical sensor works on the principle of photoelectricity. This means it is based on the conversion of light energy into electrical energy. The CY-21-PN-J utilizes an integrated phototransistor that uses a IR light to detect objects and trigger a switch in response. The integrated phototransistor has three independent receivers that allow for better accuracy and sensitivity. The sensor is also fitted with a wide angle lens to allow it to detect objects in various placements.

In its basic form, the CY-21-PN-J detects the presence, or lack thereof, of objects. It is especially well-suited for industrial applications requiring precise light measurements. Its ability to detect small objects, such as screws and nails, makes it highly useful in manufacturing and other industrial automation processes. The sensor also works for controlling access to certain locations by using its light or infrared sensors.

The CY-21-PN-J is further customizable depending on the specific requirements of the application. For instance, the light or IR sensors can be configured to detect objects within a certain size range or to respond to a specific range of light conditions. Other product features include greater protection against dust and water, and highly adjustable sensitivity and response times for increased accuracy.

The CY-21-PN-J is an inexpensive and reliable optical sensor for industrial applications. Its integrated phototransistor, wide angle lens, and other features make it well suited for a range of applications. Additionally, its ability to detect small objects, customize based on certain requirements, and provide protection against dust and water makes the CY-21-PN-J an ideal choice for industrial automation and access control projects.
