Notes: 1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 °C
+73.4 °F
.
2) The sensing range is specified for white non-glossy paper (300 × 300 mm
11.811 × 11.811 in
) as the object.
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
