Panasonic Sensor Series manual Brightness of sensor surface, Brightness of reflection surface

MA Motion Sensor (AMA1, AMB1, 2, 3)

•For thin short type:

Standard reflection board: 100 mm 3.937 inch square area, 90% reflection rate.

•For short type:

Standard reflection board: 100 mm 3.937 inch square area, 90% reflection rate.

•For middle type:

Standard reflection board: 200 mm 7.874 inch square area, 90% reflection rate.

•For long type:

Standard reflection board: 500 mm 19.685 inch square area, 90% reflection rate.

<Fig. 1>

Notes: 1. Detecting an object within the maximum preset detection distance.

2.Distance deviation = a – b × 100 (%) a

a:detection distance of detection target with reflectance of 90%.

b:detection distance of standard detection target with reflectance of 18%.
