    FAQ
    ❯

    Ambient light interference, color or material of the object being measured, dust or oil, installation angle and distance setting.

    ❯

    Infrared photoelectric sensors use invisible infrared light, are low-cost and suitable for short-range detection.

    ❯

    Ordinary infrared sensors only detect whether there is an infrared signal. Infrared sensors that can perform spectral analysis can identify the absorption characteristics of specific wavelengths and achieve accurate identification of material components.

    Helpful for a Small Automation Project
    I bought this infrared photoelectric sensor for a custom automation project in our workshop. The goal was to detect the presence of components before the next process step, and this sensor fit the requirement well. Installation instructions were clear enough, and the indicator light made alignment much easier. After testing and several weeks of operation, it has been functioning reliably with no unexpected interruptions. For a practical industrial sensing application, it has worked as expected.
