The AIMH040 Hall effect sensor measures up to ± 1000Adc and outputs a corresponding ± 5Vdc signal or a 4-20mA signal, depending on the model chosen.
The AIMH040 Hall effect sensor has a 40mm opening and has been factory calibrated so that there is no offset noise voltage to compensate for. The AIMH040 is powered by a ±15 Vdc power supply (max consumption 35mA). The AIMH040 is 1% accurate.
As with other Hall effect sensors, the AIMH040 can also measure AC frequencies, making it a popular choice when working with low frequencies that traditional CTs cannot handle.
