Honeywell advanced Hall Open-loop Current Sensor

This is an advanced Hall effect-based open-loop current sensor made by Honeywell. It could measure DC, AC or pulsating current. Users can run the cable directly through the opening (10.4mm × 20.4mm) of the current sensor without worrying about burning-up or inaccuracy because the current sensor consumes low power and there is almost no insertion loss.


  • Wired open-loop design with multiple turns for increased sensitivity
  • ac or dc current sensing
  • Linear ratiometric output
  • Current sinking or sourcing output for interfacing flexibility
  • Low insertion loss
  • Fast response time
  • Compact size for applications with limited space
  • Accurate, low-cost sensing
  • Minimum energy dissipation
  • Maximum current limited only by conductor size
  • Built-in temperature compensation promotes reliable operation
  • Operating temperature range -25 �C to 100 �C [-13 �F to 212 �F]
  • RoHs compliant (lead-free)

Typical Applications

  • Motor control in applications, HVAC and consumer tools
  • Current monitoring of electronic circuits
  • Overcurrent protection
  • Ground fault detectors
  • Robotics
  • Industrial process control
  • UPS and telecommunication power supplies
  • Welding current monitoring
  • Battery management systems in mobile equipment
  • Watt meters
  • Variable speed drives
