JM21FA/NA Series: Split-core Current Transducer

The JM21FA/NA Split-core Current Transducer delivers high-accuracy AC waveform measurement while ensuring complete galvanic isolation between the primary conductor and the low-voltage signal chain. Its hinged, split-core housing clips around live cables no downtime or rewiring making it ideal for energy-management, HVAC control and industrial automation.

Field-selectable 0-5 VDC, 0-10 VDC or 4-20 mADC outputs integrate seamlessly with PLCs, SCADA systems and IoT gateways, while rugged insulation and wide current-range options safeguard downstream electronics against surges and noise. Certified to international safety standards, the JM21FA/NA helps engineers achieve reliable, non-intrusive current sensing and faster system-level installs.
