KUALA LUMPUR, May 24 (Bernama) -- Crocus Technology Inc, the leading supplier of disruptive TMR (Tunnel Magneto-Resistance) XtremeSense® sensors, has announced the CT45x family of contactless isolated current sensors to enable high precision and high current measurements in a more simplified solution.
“With the introduction of the CT45x family of contactless current sense products, we now have a complete portfolio of products for our customers from small currents to larger currents,” said President and CEO of Crocus Technology, Zack Deiri.
“This product based on Crocus’ cutting-edge TMR technology is the most exciting for us as the benefits of our XtremeSense TMR are addressing the needs of higher current applications that can’t be met with existing solutions without compromises.”
According to a statement, unlike existing solutions, the CT45x allows manufacturers to eliminate costly shields, concentrators or cores.
The CT452 and CT453 offers contactless 0.7 per cent accuracy, 1 MHz bandwidth, and better than -50 dB immunity to external magnetic fields without additional mechanical components.
This combination of performance and accuracy enables customers to reduce their overall product size and weight which enables them to replace large and costly current sense modules with a small and simple solution.
The CT45x products are based on XtremeSense TMR technology that delivers the future with a high signal-to-noise ratio (SNR) contactless approach which can scale with the system requirements, high bandwidth and fast response time, common-model field rejection, combined with high accuracy measurements over temperature.
The CT45x offers groundbreaking noise performance, as low as 0.55 mVRMS, to enable applications to sense small current levels and small changes or variations in current through a busbar.
This performance is almost 10 times better than existing Hall Effect solutions. This results in a SNR (signal-to-noise ratio) as high as 77 dB for the CT45x measurement which allows the system to process higher resolution data with higher accuracy.
