Digital Hall-sensors
Supply of sensors: Voltage range: 4.5 to 5.5 V DC / Optional: voltage regulator for 5 V, Input current: < 70 mA Output signals of sensors: Differential output (RS422 standard, datasheet AM26 C31-TI)
Typical voltage range: 0.2/ 3.4 V @ 20 mA, Output current: max. 20 mA
Signal structure: The Hall sensors have a 120° phase shift to each other. Due to the 14-pole design the Signal frequency is seven times higher than the speed
