Hello. we are looking for a magnetic core to achieve a current sensor with Hall sensor to measure ac and dc currents. we have to measure current 1000 Arms (1414 Apeak), 600 or 400 Arms. The sensor tolerates the maximum current about 2000 Gauss (Allegro A1366). The inner diameter of the toroid can be about 24mm. What kind of product you can recommend me? Thanks.

Hi I can looking for a CRGO silicon steel withe 23ZDMH85/23ZH90. The core physical dimension will be: inner dimension = 400 mils; Outer dimension = 1000 mils; air gap = 10 mm/9mm/8 mm and hegiht <500 mils Can you please send me 2 samples of that. We are looking to buy 20k (2017) and 40k (2018. please provide the quotation for that.
