    Types of pyroelectric infrared sensors

    The pyroelectric infrared sensors offered by 萝莉影视 can largely be divided into the following types.

    Dual type
    for human body detection in a wall-mounted set
    Quad type
    for human body detection in a ceiling-mounted set

    The dual type commercializes high-sensitivity and dual type sensors for sets used outdoors.

    We offer a lineup of dual type (wall-mounted type) and quad type (ceiling-mounted type) RFI suppression products with enhanced electromagnetic wave resistant characteristics.

    • *Please inquire about products with different output types.

    (IRA-S510ST01)     		Standard for ceiling mount type application
    If you are considering sensors for outdoor use

    We would ask that you refrain from using pyroelectric infrared sensors in locations where they are exposed to direct sunlight, but there are also examples of using the sensors outdoors by devising ways to prevent direct sunlight from hitting the sensor area (lens section). We recommend the use of the IRA-S220ST01A01 / IRA-S230ST01 models which are resistant to temperature changes due to their internal structure.

    If you wish to improve the noise performance for radio waves

    We offer a lineup of sensor types with improved noise resistance performance. The effectiveness for malfunctions due to radio wave noise differs by circuit and substrate conditions. Therefore, first check and see if they have an effect on problematic sets.
