Description
CT220BMV-HS5 Contactless Current Sensor Carrier Module is a compact board featuring a sensor from Allegro Microsystems, based on XtremeSense™ TMR (Tunnel MagnetoResistance) technology, designed for non-contact current measurement.
This solution enables precise current measurement without breaking the circuit – the sensor detects the magnetic field generated by current flowing through a nearby conductor. TMR technology ensures high sensitivity and low power consumption, making it ideal for energy-efficient applications.
The device offers high linearity, resolution, and temperature stability, while maintaining excellent electrical isolation. The analog output, proportional to the magnetic field strength, allows for accurate current measurements after proper calibration. The sensor operates in bidirectional mode, supporting both DC and AC systems. Its compact size and mounting holes allow for easy attachment to a wire. The JST SH connector and 2.54 mm pitch through-holes provide flexible connectivity options. Additionally, the FLAG output signals when the magnetic field exceeds a specified threshold. This module is an ideal solution for projects that require safe and reliable current monitoring.
CT220BMV-HS5 supports a magnetic field range of ±1.5 mT (±15 G). It offers output sensitivity of 1500 mV/mT at 5 V supply voltage or 990 mV/mT at 3.3 V. The sensor operates at a supply voltage range of 2.7 V to 5.5 V, with a zero-output voltage of 2.5 V at 5 V supply. The actual current measurement range and sensitivity depend on the distance between the sensor and the conductor, its geometry, and orientation relative to the board. For best results, it is recommended to calibrate the sensor in the target setup, especially for varying wire diameters and insulation thicknesses.
