Hall Effect Zero Speed and Active Sensors

Hall effect speed sensors are also called Zero Speed Sensors and Active Speed Sensors


Hall Effect Sensors:

  • Is an active, powered device that produces an output signal regardless of target speed from zero 15kHz+
  • It includes a silicon chip that has high level of circuit integration leading to high reliability
  • Typical output from a Hall Effect Sensors is Digital, square-wave output; amplitude is independent if speed
  • 3 wire connection (single channel), 5 wire connection (dual channel with direction)
  • Very stable over wide temperature range -40C to +125C




Principle of Operation – Single Element vs. Differential


Single Element

RH Series – no need for alignment




BH, DH Series – requires alignment

Hall Effect Speed Sensor Features:

  • High temperature range of -40C to +125C
  • Wide range of supply voltage; 4.5-24Vdc (single channel) and 10-28Vdc (dual channel)
  • Two output options of Supply Tracking or TTL Compatible
  • Increased air gap capability over VR Sensors; no loss of signal amplitude
  • Output signal will react to the lowest increment of speed without loss of amplitude
  • High level of intrinsic noise immunity
  • Vibration Immunity

Hall Effect Speed Sensor Benefits:

  • Easy installation
  • No alignment for RH series sensors
  • High reliability
  • Direction Indication
  • Reverse voltage protection, up to -30 Vdc, to prevent damage if mis-wired

Hall Effect Speed Sensor Limitations:

  • Temperature – Max temp is 125C
  • Not good with axial trajectory targets
