CT220

XtremeSense® Sensor

High Linearity/High Resolution Contactless Current Sensor

Data Sheets

The CT220 is a high linearity and high-resolution contactless current sensor from Crocus Technology developed on its patented XtremeSense® TMR technology with the capability of measuring up to 1,000 A. It measures the magnetic field of the current flowing through a busbar or printed circuit board (PCB) trace and converts it to an analog output voltage that represents the field and therefore current.

The CT220 is an ideal contactless current sensing solution for applications that need to have excellent isolation and accurate current measurements. There are four (4) variants of the CT220 that will sense the following magnetic fields: ±1.5 mT, ±5.0 mT, ±10.0 mT and ±15.0 mT.
