Current Sensors
Programmable, open-loop and closed-loop Hall sensors, digital-signal sensors, transmitters, high-precision, and multi-channel families.
Family Overview
This page focuses on current sensor families. EV charging leakage and Type A + DC 6mA RCD products remain in the existing RCD sensor catalog.
Hall current sensors
Programmable Hall current sensors using integrated Hall ICs and calibration for compact inverter, combiner box, and embedded power electronics applications.
New energy current sensors
Current sensors for battery management, electric drive, and electronic control systems where compact packaging and stable Hall measurement are required.
Open-loop Hall current sensors
Open-loop Hall current sensors for fast-response and cost-effective monitoring in welding machines, frequency converters, power supplies, drives, and industrial systems.
Closed-loop Hall current sensors
Closed-loop Hall current sensors using magnetic balance principles for high accuracy, strong linearity, low drift, and fast response in drive and power systems.
Digital current sensors
Digital current sensors with CAN or RS485 output for DC, AC, and pulsed current measurement in electric vehicles, plug-in hybrid vehicles, and energy storage systems.
Current transmitters
Current transmitters converting measured AC current into standard DC output signals for receiving devices, computers, display instruments, and control systems.
High precision current sensors
High-precision current sensors for applications requiring very high accuracy, strong linearity, low temperature drift, and ppm-level performance.
Multi-channel current sensors
Multi-channel current sensors that measure multiple circuits or multiple current ranges for BMS, electric drive control, and compact multi-channel monitoring.
EV Current Measurement
Select a current measurement family around the controller interface and the circuit being measured. For battery management and electric drive projects, review thenew energy current sensors andmulti-channel sensor families. For a CAN or RS485 interface, compare thedigital current sensors.
Send the nominal and peak current, supply voltage, output interface and available mounting space with your inquiry. The ranges below summarize each family; confirm the combination of ratings for the specific model in its datasheet. For residual current detection in an EV charger, see theType A + DC 6mA RCD sensor catalog.
