Automotive Open Loop Current Sensor


current sensorPiher Sensing Systems launches an open loop current sensor that generates a ratiometric analog output voltage signal proportional to the current flowing through the conductor.

Based on Hall effect technology the sensor has been designed for accurate measurement of currents in automotive battery management and motor control applications.

  • Open loop current transducer based on Hall effect
  • Measured current values from ±200 A to ±1,500 A
  • Simple or redundant analog ratiometric output
  • Non-intrusive technology
  • Galvanic separation between power and control

Current measurement range

±200 A, ±300 A, ±400 A, ±500 A, ±700 A, ±800 A, ±1000 A, ±1200 A, ±1500 A
