I'm having a problem with the measurement with this sensor, the sensor data sheet does not give me information that hits with the sensors I have, the data sheet DVR5053 of the hall sensor does not talk about specs coming in the sensor, for example my sensors printed in them acronyms as 4C2CF alca and in the other 580YF alca. and my biggest doubt is, how many tesla can I measure with these sensors and how sensitive are they to the making of the cover? because in the data sheet it has values like - 11mv / mT (OA), - 23 mV / mT (PA). these acronyms OA and PA can not find fault in the sensor. I hope you can help me. Thank you.
