Littelfuse CH1B02xB & CH1B02xM Current Sensors

Littelfuse CH1B02xB and CH1B02xM Current Sensors are designed for automotive applications and utilize open-loop Hall effect technology. These devices provide a ratiometric output signal proportional to the magnetic flux density generated by a C-core concentrator. This high-accuracy, non-intrusive solution offers low thermal offset drift and low thermal sensitivity drift. Additional features include single- or dual-channel output, a current measurement of up to ±1500A, and a +5VDC unipolar power supply. These automotive current sensors from Littelfuse offer an IP4X protection and an operating temperature range of -40°C to +125°C. The lineup includes three configurations: a standard connector, a standard connector with a cable retainer, and a CPA-equipped connector. The CH1B02xB sensors are suitable for battery management, while the CH1B02xM series is ideal for motor control applications.
