Optical sensors are devices used to detect the presence, absence, or change of an input signal by converting light energy into an electrical signal. They are widely used in industrial automation, monitoring, and security. As an example of an optical sensor, the ZX-SD301 0.5M has applications in industrial automation, as well as other areas. This article will discuss the application field and working principle of the ZX-SD301 0.5M optical sensor.

Application Field

The ZX-SD301 0.5M optical sensor is designed for use in industrial automation. It can be used for the detection and measurement of a variety of objects, including paper goods, various metals, plastic, wood, glass, and organic materials. It can also be employed for inspecting elements with large surface area, such as wafers and printed circuit boards. Additionally, the ZX-SD301 0.5M can be used for the detection and measurement of other materials, such as oil, water, and steam. It is also suitable for use in extreme environments, due to its IP67 water-tight ratings. The operating temperature range is from -20℃ up to +55℃.

Working Principle

The ZX-SD301 0.5M utilizes a transmissive optical sensing head to collect light reflected from the detected object or surface. The optical sensing head is equipped with a built-in high power infrared LED, providing narrow directional beams of light that propagates along the object. An optical lens accurately focuses the light beam, increasing its intensity.

The light that is reflected back from the object is detected by a photo-diode. Based on the magnitude of the reflected light, the photo-diode produces an analog signal which is then sent to the associated control unit. The control unit then converts the analog signal into a digital signal, which can then be further processed and used in accordance with the specific requirements of the application.

The ZX-SD301 0.5M is a fast response optical sensor, providing accurate detection results within a few milliseconds. The false trigger rate is low, providing reliable performance. Additionally, the sensor has excellent immunity to EMI Our ESD, which prevents accidental activates due to external factors.

Conclusion

The ZX-SD301 0.5M is an optical sensor designed for industrial automation applications. It is equipped with a transmissive optical head, which is used to detect the presence, absence, or change of an input signal by converting light energy into an electrical signal. Its fast response time ensures accurate detection results within milliseconds, while the immunity to EMI and ESD provides reliable performance.
