Open-type magnetic current sensor corresponding to the safety standards CQ-223x/CQ-233x

Tokyo Japan, April 2 2014, Asahi Kasei Microdevices Corporation (AKM) had launched CQ-223x and CQ-233x lineups.

CQ-223x and CQ-233x are open-type magnetic current sensors with the best accuracy including temerature drift.

Space-saving, highly-reliable AI-ShellTM(*1) package and fastest response time among open-type current sensor

are best suited to current detection of inverter circuit.

Certification of IEC/UL safety standards will assure of the high-voltage usage for industrial application.
