FERRTX Closed Loop Hall Effect Current Sensor HKC｜Zero Hysteresis & 10kHz Bandwidth

Precision Current Sensing Revolution

The FERRTX HKC Series Closed Loop Hall Effect Current Sensor delivers laboratory-grade accuracy in harsh environments. Leveraging magnetic compensation technology, it achieves ±1% linearity across DC-10kHz bandwidth – outperforming traditional DC Current Sensors in dynamic response. With reinforced 5kV galvanic isolation and -40°C to +125°C operation, it replaces bulky lem split core current sensor solutions in space-constrained applications.

Core Engineering Advantages

Eliminates calibration drift vs. open-loop?hall effect current sensors
Sub-μs Response Time
5× faster than?Rogowski Current Sensors?for overcurrent protection
Wide Voltage Compatibility
4.5-24V supply range (TTL/CMOS compatible)
EMC Immunity
Withstands 100V/ns dv/dt noise in VFD environments
