LEM introduces family of current sensors for automotive battery-monitoring applications

The sensors are based on open-loop, Hall-effect transducers that simplify both installation and servicing by removing the need to cut the cable carrying the measured current. They operate from a unipolar 5V supply and provide a fully ratio metric solution for the voltage output devices. Response time is less than 10ms.

A watertight housing and sealed connector provide full environmental protection in under-bonnet applications.

Principal applications are expected to be in the measurement of battery-pack current in electric, hybrid and conventional vehicles.
