ambient temperature：+20℃、
Reaction time： 10ms、Analog output value for measuring center distance.
Object：White ceramic. (Note 2): Based on the provisions of Laser Notice No. 50 of FDA regulations and based on FDA.
This value is measured at the center distance. Define these values in terms of 1/e2 (approximately 13.5%) of the central light intensity. If there is light leakage outside the defined area and there are strong reflections around the detection point that are higher than the detection point itself, the detection results may be affected.

Notice：
Do not use this product as a detection device to protect personal safety.
For detection devices designed to protect the human body, please use products that comply with OSHA, ANSI, IEC and other countries' laws and standards on human protective equipment.
Do not operate according to methods not described in the instructions for use that come with the product. If you perform controls or adjustments other than those specified, you may be exposed to dangerous radioactive laser light.
This product is a Class 2 laser product that complies with JIS/IEC/GB standards or a Class II laser product that meets FDA regulations. This product has certain dangers. Please do not look directly at the laser or observe it through a lens, etc.
relative to the direction of the moving body
<In case of material and color difference>
When measuring, when the moving measurement objects have extremely different materials and colors, install them in the direction shown in the figure below to minimize the measurement error.
<Detect rotating objects>
When measuring a rotating object, install it in the direction shown in the figure below to suppress the effects of vertical vibration and positional deviation of the object.
<When there is a step difference>
If there is a step in the moving detection target, install it as follows to suppress the influence of the edge of the step during measurement.
Measure in tight places and recessed parts.
When measuring in a narrow place or hole, be careful not to block the light path from the emitter to the receiver when installing.
When mounted on the wall
Please install according to the following methods to prevent multiple reflections from the wall from entering the light-receiving part. In addition, if the reflectivity of the wall is high, the effect will be better if it is changed to matte black.
