AKM Current Sensors, CQ Series
 |
| |
AKM (Asahi) Current Sensors have full scale current ranges are ±25A and ±55A with frequency response from dc to over 50kHz. The “CQ series” uses a magnetic core enclosing the primary conductor and a very high performance linear Hall effect IC. This structure creates a high accuracy, low noise, reduced cross-talk sensor with minimized influence from external magnetic fields. The sensor size is 8 x 20 x 14 mm, the smallest size of a core type current sensor for the current ranges.
