Zetex ZMC05TA, ZMC05TC Datasheet
CURRENT SENSOR
DESCRIPTION
The ZMC05 allows the measurement direct or alternating current up to 5A. It
consists of a magnetic sensor chip (employing the magneto resistive effect of thin
Permalloy), which measures the magnetic field generated by an internal-carrying
conductor.
