FEATURES

• Package : mod. DIL-14

• A magnetic sensor chip (employing the

magnetoresistive effect of thin film permalloy)
measures the magnetic field generated by an
internal current-carrying conductor

• measurable direct or alternating current I

20A

• supply voltage 12 V

• no auxiliary field H

• it’s possible to overload the conductor (between

pin’s 8,9,10 and 11,12,13) with 300A for 10 ms
