Crocus magnetic current sensors offer contactless current sensing by measuring the magnetic field of a current carrying conductor. The CT219 differential current sensor offers a compelling alternative to current transformers, Hall, AMR and GMR sensors. All products are designed for applications that require high accuracy, wide dynamic range, small form factor, and low power.
