Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 °C +73.4 °F.
2) Obtain the current consumption from the following equation.
Current consumption = Power consumption ÷ Supply voltage
(e.g.) In case of NA2-N8 (when job indicator lights up)
When the supply voltage is 12 V, the current consumption of the emitter is: 0.7 W ÷ 12 V ≈ 0.058 A = 58 mA.
