Speed sensor (digital differential magneto resistor)
Trouble-free evaluation requires good wiring.
Ü
Use twisted and shielded cables.
Ü
Connect the HF spindle based on the connection example shown below.
DFP = digital differential magneto
resistor
S = signal
Note: Resistor (Rx).
If the resistor (Rx*) is already integrated in the evaluation unit (FC):
u
Only connect signal and ground.
