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
Differential
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
