5.4.5 Connecting the Power Supply
Figure 6: Connecting the sensor power supply
The FFD sensor requires a power supply of between 16 V and 24 V DC @ 80 mA.
NOTE:
Keep the length of exposed screen (known as a ‘pigtail’) to an absolute minimum (long pigtails degrade EMC
performance); however, the signal wires may be longer.
