Note 1: Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 ℃ +73.4 ℉.

Note 2: The sensing range is specified for white non-glossy paper (300 x 300 mm 11.811 x 11.811 in) as the object.

Note 3: Obtain the current consumption by the following calculation.
Current consumption = Power consumption ÷ Supply voltage
(e.g.) When the supply voltage is 12 V, the current consumption (operating condition) is: 1.5 W ÷ 12 V = 0.125 A = 125 mA
